Linus Torvalds has announced the release of Linux kernel 6.11, which is the kernel version Ubuntu 24.10 and Ubuntu 24.04.2 LTS will offer. Fittingly, this update arrives a few days before the Linux Kernel Maintainer Summit takes place in Vienna, Austria. In his message to the Linux Kernel Mailing List to sign-off on the release Torvalds' writes: "I'm once again on the road and not in my normal timezone, but it's Sunday afternoon here in Vienna, and 6.11 is out", and asks kernel devs to "give the latest release a try" before getting stuck in with the 6.12 merge window, […]

Parasocial chat

On Linux Matters we have a friendly and active, public Telegram channel linked on our Contact page, along with a Discord Channel. We also have links to Mastodon, Twitter (not that we use it that much) and email.

At the time of writing there are roughly this ⬇️ number of people (plus bots, sockpuppets and duplicates) in or following each Linux Matters "official" presence:

Preponderance of chat

We chose to have a presence in lots of places, but primarily the talent presenters (Martin, Mark, and myself (and Joe)) only really hang out to chat on Telegram and Mastodon.

I originally created the Telegram channel on November 20th, 2015, when we were publishing the Ubuntu Podcast (RIP in Peace) A.K.A. Ubuntu UK Podcast. We co-opted and renamed the channel when Linux Matters launched in 2023.

Prior to the channel's existence, we used the Ubuntu UK Local Community (LoCo) Team IRC channel on Freenode (also, RIP in Peace).

We also re-branded our existing Mastodon accounts from the old Ubuntu Podcast to Linux Matters.

We mostly continue using Telegram and Mastodon as our primary methods of communication because on the whole they're fast, reliable, stay synced across devices, have the features we enjoy, and at least one of them isn't run by a weird billionaire.

Other options

We link to a lot of other places at the top of the Linux Matters home page, where our listeners can chat, mostly to eachother and not us.

Being over 16, I'm not a big fan of Discord, and I know Mark doesn't even have an account there. None of us use Twitter much anymore, either.

Periodically I ponder if we (Linux Matters) should use something other than Telegram. I know some listeners really don't like the platform, but prefer other places like Signal, Matrix or even IRC. I know for sure some non-listeners don't like Telegram, but I care less about their opinions.

Part of the problem is that I don't think any of us really enjoy the other realtime chat alternatives. Both Matrix and Signal have terrible user experience, and other flaws. Which is why you don't tend to find us hanging out in either of those places.

There are further options I haven't even considered, like Wire, WhatsApp, and likely more I don't even know or care about.

So we kept using Telegram over any of the above alternative options.

Pondering Posting Polls

I have repeatedly considered asking the listeners about their preferred chat platforms via our existing channels. But that seems flawed, because we use what we like, and no matter how many people prefer something else, we're unlikely to move. Unless something strange happens 👀 .

Plus, often times, especially on decentralised platforms, the audience can be somewhat "over-enthusiastic" about their preferred way being The Way™️ over the alternatives. It won't do us any favours to get data saying 40% report we should use Signal, 40% suggest Matrix and 20% choose XMPP, if the four of us won't use any of them.

Pursue Podcast Palaver Proposals

So rather than ask our audience, I thought I'd see what other podcasters promote for feedback and chatter on their websites.

I picked a random set from shows I have heard of, and may have listened to, plus a few extra ones I haven't. None of this is endorsement or approval, I wanted the facts, just the fax, ma'am.

I collated the data in a json file for some reason, then generated the tables below. I don't know what to do with this information, but it's a bit of data we may use if we ever decide to move away from Telegram.

Presenting Pint-Sized Payoff

The table shows some nerdy podcasts along with their primary means (as far as I can tell) of community engagement. Data was gathered manually from podcast home pages and "about" pages. I generally didn't go into the page content for each episode. I made an exception for "Dot Social" and "Linux OTC" because there's nothing but episodes on their home page.

It doesn't matter for this research, I just thought it was interesting that some podcasters don't feel the need to break out their contact details to a separate page, or make it more obvious. Perhaps they feel that listeners are likely to be viewing an episode page, or looking at a specific show metadata, so it's better putting the contact details there.

I haven't included YouTube, where many shows publish and discuss, in addition to a podcast feed.

I am also aware that some people exclusively, or perhaps primarily publish on YouTube (or other video platforms). Those aren't podcasts IMNSHO.

Key to the tables below. Column names have been shorted because it's a w i d e table. The numbers indicate how many podcasts use that communication platform.

• EM - Email address (13/18)
• MA - Mastodon account (9/18)
• TW - Twitter account (8/18)
• DS - Discord server (8/18)
• TG - Telegram channel (4/18)
• IR - IRC channel (5/18)
• DW - Discourse website (2/18)
• SK - Slack channel (3/18)
• LI - LinkedIn (2/18)
• WF - Web form (2/18)
• SG - Signal group (3/18)
• WA - WhatsApp (1/18)
• FB - FaceBook (1/18)

Not entirely sure what to do with this data. But there it is.

Is Linux Matters going to move away from Telegram to something else? No idea.

Ubuntu 24.10 features a clutch of headline-worth changes, but also plenty of less obvious fixes for "paper cuts" - including a decades-long issue with thumbnails in the GTK file picker. Feeling deja-vu? GNOME 44 (shipped in Ubuntu 23.04) included a thumbnail grid in the GTK file picker to make it quicker and easier to select the right files to upload, or open in an app, and so on. A feature long overdue, resolving a "bug" which had been open for 20 years! Only, there is a bit of a problem with how it works - some of you may have […]

The fifth and final point release to Ubuntu 22.04 LTS is now available to download. This update was due to be released a couple of weeks ago but was delayed by a delay in getting Ubuntu 24.04.1 LTS out the door - something had to give, so the release date of this update slipped. But it's here now, ready to download. Ubuntu 22.04.5 LTS brings a freshly-spun installer image (ISO) that includes all of the software, security, and stability updates released since the last ISO was made.

The Cinnamon desktop environment looks pretty nice on Linux Mint, but if you install it on other distributions it doesn't look as good - but that's about to change. In his latest monthly mail-shot, distro lead Clement Lefebvre says the "ugly" default Cinnamon theme, which is maintained for trouble-shooting and testing purpose and is not the theme Linux Mint itself sets as default, will be "much improved" in Cinnamon 5.4. "In our distribution the focus is on Mint-Y. The default Cinnamon theme […] rarely gets attention from theme artists," he says. "Ideally, it is the responsibility of the distributions to […]

Report by Omdia and Canonical finds network cloudification a key priority, shows CSPs embracing open source technologies

London, UK. 12 September 2024. Today, Omdia and Canonical, the publisher of Ubuntu, released a new research report which indicates that communications service providers (CSPs) in the US, UK and Germany increasingly view networked edge computing not just as a long-term priority, but as an opportunity that will generate returns in the near future. The report, entitled "Cloud-native network transformation and the 5G edge", finds that realising the full potential of 5G networks is a priority that CSPs are tackling with increased optimism.

After a slow start, CSPs see potential in 5G networked edge computing

Until a few years ago, concerns about the absence of a "killer app" to drive the growth of 5G networked edge computing fueled uncertainty among CSPs about use cases and demand. The research report shows, however, that this situation has changed dramatically, driven partly by the growth of interest in AI-powered use cases. In fact, 86% of CSPs are optimistic about the future of edge computing on telco networks.

This optimism is driving action: CSPs are now ramping up their efforts to become cloud-native in order to adopt a streamlined, mature approach to networked edge computing. The research reports that 90% of CSPs who don't already have a full commercial edge computing deployments in place, plan to complete it within the next two years.

CSPs' expected timeframe for completing commercial deployment of edge computing

Cloud-native technologies essential for unlocking $26bn networked edge opportunity

Almost all respondents reported expecting some (60%) or substantial (39%) new revenue to come from edge computing in future. It's easy to see why: when computing comes closer to end users and devices, and is integrated with network functions, workloads can be optimised for low latency and bandwidth savings while applications can run near or within customer premises to satisfy privacy, control and performance requirements.

All the optimism, confidence in demand, and growth expectations, along with expansion plans of edge infrastructures will translate to an overall market growth. Omdia expects networked edge uptake to grow over the next several years, leading to an opportunity of more than $26bn of IaaS and SaaS by 2032.

Networked edge servers (installed base) and related IaaS + SaaS revenue, 2022-2032

CSPs recognise, however, that network cloudification will be essential for capturing the edge computing opportunity. The survey found that network cloudification across all network domains, core, RAN, and transport, is the biggest expected driver of edge computing for telcos.

Kerem Arsal, Senior Principal Analyst at Omdia elaborates, "Our research shows that networked edge computing will grow and mature significantly over the next several years," and added that "CSPs recognise that network cloudification will be key in capturing edge computing opportunities. They see becoming cloud native as a big priority due to its many benefits - both from technical and operational perspectives."

Technical issues, interoperability and network readiness among key pain points for CSPs

Undoubtedly, CSPs are still facing challenges in making the benefits of edge computing a reality. The research sought to explore the nuances of these challenges. The majority of CSPs identified technical issues, such as clashes between cloud and legacy systems, as the primary barriers to deploying edge applications. Network readiness for edge computing, specifically lack of progress on vRAN, 5G core and containerisation, was also highlighted as a key hurdle. Enhancing interoperability through network cloudification was identified as a priority for overcoming these challenges.

Cloud-native technologies can be instrumental in addressing many of these challenges. Cédric Gégout, VP of Product at Canonical, explains: "Becoming cloud-native goes beyond networked edge computing. It's about using platforms like Kubernetes, LXD, and OpenStack to unify diverse systems. Combined with the interoperability offered by open source components, like Ceph for distributed storage and OVN for software defined networking, this helps automate and orchestrate everything from deployment and maintenance to continuous optimisation. By adopting cloud-native technologies, CSPs can make their networks more flexible, enabling faster deployment of new services like AI-driven management and real-time analytics. This approach not only boosts efficiency but also keeps CSPs competitive, ready to capitalise on the new coming opportunities in network edge computing."

It's essential that CSPs view becoming cloud-native as more than a way to reap the benefits of networked edge computing. It should be approached as a solid strategic move that will also result in a better experience for existing customers, one that can open up new revenue streams, and overcome persistent hurdles.

Read the report for a full overview of the benefits and challenges that are driving networked edge computing.

Incus is a manager for virtual machines, system containers and application containers. Get Incus support here.

When you initially setup Incus, you create a storage pool where Incus will put in there everything. There are several options for storage pools, in this post we focus on ZFS storage pools, and those specifically that are stored on a separate block device (like /dev/sdb).

We are dealing with two cases. One, your installation of Incus has been somehow removed but the storage pool is somewhere there intact and you want to recover by installing again Incus. Two, you want to move the disk with storage pool from one computer to another, like reconnecting the storage pool on a new server.

This type of task is quite risky if you have a lot of important data on your system. Obviously, prior to you actually doing this on an actual system, you should take backups with incus export of your most important instances. And then, you should perform this tutorial several times so that you get the gist of recovering Incus installations. This tutorial shows you how to do a dry run of creating an Incus installation, killing it off, and then miraculously recovering it.

Prerequisites

You should have a running Incus installation.

Setting up Incus, using a block storage volume

We launch an Incus virtual machine (VM) that will act as our Incus server. We then (on the host) create a storage volume of type block. Next, we attach that block storage volume to the VM. In the VM it can be found as /dev/sdb. Subsequently, we incus admin init to initialize Incus, and configure Incus to use the block device /dev/sdb when creating the storage pool. When we run incus admin init, we press Enter when we want to accept the default value.

$ incus launch images:ubuntu/24.04/cloud --vm incusserver
Launching incusserver
$ incus storage volume create default IncusStorage --type=block size=6GiB
Storage volume IncusStorage created
$ incus storage volume attach default IncusStorage incusserver
$ incus shell incusserver
root@incusserver:~# fdisk -l /dev/sdb
Disk /dev/sdb: 6 GiB, 6442450944 bytes, 12582912 sectors

Sector size (logical/physical): 512 bytes / 512 bytes

      path: /
      pool: default
      type: disk
  name: default
projects: []
cluster: null

root@incusserver:~#

Next we populate the Incus installation with a few alpines. We do this because we want to see these containers again after we recover the storage pool.

root@incusserver:~# incus launch images:alpine/edge alpine1
Launching alpine1
root@incusserver:~# incus launch images:alpine/edge alpine2
Launching alpine2
root@incusserver:~# incus launch images:alpine/edge alpine3
Launching alpine3
root@incusserver:~#

This is where the interesting stuff start. We now want to shutdown the Incus server and remove it. However, the block storage volume will still be there and in good condition, as the server has been shutdown cleanly. Note that the block storage volumes should only be attached to one system at a time.

root@incusserver:~# shutdown -h now
root@incusserver:~# Error: websocket: close 1006 (abnormal closure): unexpected EOF
$ incus storage volume show default IncusStorage

description: ""

location: none
content_type: block

$

Next, we launch a new VM that will be used as a new Incus server, then attach back the block storage volume with incus storage volume attach and install Incus along with the necessary ZFS client utils.

Finally, we bring back the old installation data with those three alpines. We run zpool import, which is a ZFS command that will look for potential ZFS pools and list them by name. The command zpool import default is the one that does the actual import. The ZFS pool name default was the name that was given by Incus before, when we were initializing Incus. Subsequently, we run incus admin recover to recover the ZFS pool and reconnect it with this new installation of Incus.

Setting Up Rig Control and CAT Interfaces

One of the key aspects of setting up a ham shack on Ubuntu is ensuring seamless communication between your computer and radio equipment. This usually involves setting up rig control and Computer-Aided Transceiver (CAT) interfaces. The Hamlib library mentioned earlier is crucial for this.

• Rig Control Setup: Use rigctl (part of Hamlib) to set up rig control. You may need to specify the serial port or USB port where your rig is connected:

  rigctl -m <radio_model_number> -r /dev/ttyUSB0 -s <baud_rate>

• Testing the Interface: Once set up, test the interface to ensure commands from the computer are correctly interpreted by the radio.

Customizing Ubuntu for Ham Radio Use

To optimize Ubuntu for your ham shack, consider the following:

1. Disable Unnecessary Services: Disable services that aren't needed to reduce system load.
2. Optimize Audio Settings: Properly configure ALSA and PulseAudio settings to ensure clear and reliable audio communication.
3. Set Up a Backup System: Use tools like rsync or Timeshift to set up regular backups of your log files and settings.
4. Use Virtual Desktops: Take advantage of Ubuntu's multiple desktops feature to separate your ham radio operations from general computing tasks.

Conclusion

Using Ubuntu as your ham shack operating system offers flexibility, stability, and a wide range of powerful software tools. Whether you're a digital mode enthusiast, a satellite tracker, or someone who loves experimenting with different radio setups, Ubuntu provides an open, customizable platform that can meet your needs.

In an era where digital privacy is increasingly at risk, securing your DNS (Domain Name System) queries is crucial. Traditional DNS requests are sent in plaintext, making them vulnerable to eavesdropping and tampering. Fortunately, DNS over HTTPS (DoH) and DNS over TLS (DoT) offer encrypted channels for DNS queries, significantly enhancing your privacy and security.

In this guide, we'll explore how to set up your own personal DNS resolver using open-source software that supports both DoH and DoT. We will cover the installation and configuration of Unbound, Caddy, Stubby, and other relevant tools to ensure your DNS traffic remains private and secure.

Understanding DoH and DoT

• DNS over HTTPS (DoH): Encrypts DNS queries using the HTTPS protocol, making it difficult to distinguish DNS traffic from regular web traffic. This helps bypass censorship and improve privacy.
• DNS over TLS (DoT): Encrypts DNS queries using Transport Layer Security (TLS), securing the communication channel between your device and the DNS resolver.

Both protocols prevent eavesdropping and manipulation of DNS data by external parties, such as ISPs or malicious actors.

Why Run Your Own DNS Resolver?

Running your own DNS resolver has several advantages:

1. Enhanced Privacy: Prevent third-party DNS services from logging or selling your DNS queries.
2. Increased Security: Protect against DNS hijacking and other DNS-related threats.
3. Customization: Apply custom DNS filtering rules, block ads and trackers, or direct specific domains to chosen IPs.
4. Improved Performance: Reduce latency by caching DNS responses and optimizing resolver placement.

Open-Source Software for DoH and DoT

We'll focus on the following open-source tools to set up a personal DNS resolver with support for DoH and DoT:

1. Unbound: A high-performance DNS resolver that supports DNS over TLS (DoT).
2. Caddy: A modern web server with native support for DNS over HTTPS (DoH).
3. Stubby: A DNS privacy daemon designed for DNS over TLS (DoT).
4. Knot Resolver: A versatile DNS resolver supporting both DoH and DoT.
5. CoreDNS: A DNS server with modular support for DoH and DoT via plugins.
6. DNSDist: A DNS load balancer that can proxy DNS queries over HTTPS and TLS.

Protect your online privacy and enhance your security by setting up your personal DNS resolver with DNS over HTTPS (DoH) and DNS over TLS (DoT). Learn how to install and configure popular open-source tools like Unbound, Caddy, Stubby, Knot Resolver, CoreDNS, and DNSDist to secure your DNS queries.

When development on system info tool Neofetch was discontinued1 earlier this year a slew of forks, alternatives, and upstart projects sprung up to fill the void. Yet the Neofetch alternative that's gained the most traction -anecdotally, at least; I've not be creeping around Linux conferences to verify first-hand-is Fastfetch. Fastfetch is similar to Neofetch in that it 'pretty prints' information about your OS, desktop environment, pertinent underlying technologies, and selected system hardware specs in a terminal window. But Fastfetch is far more capable than Neofetch: it's faster, more featured2, supports Wayland (Neofetch technically didn't), and is actively maintained. Indeed, the […]

This is mostly an informational PSA for anyone struggling to get Windows 3.11 working in modern versions of QEMU. Yeah, I know, not exactly a massively viral target audience.

Anyway, short answer, use QEMU 5.2.0 from December 2020 to run Windows 3.11 from November 1993.

An innocent beginning

I made a harmless jokey reply to a toot from Thom at OSNews, lamenting the lack of native Mastodon client for Windows 3.11.

When I saw Thom's toot, I couldn't resist, and booted a Windows 3.11 VM that I'd installed six weeks ago, manually from floppy disk images of MSDOS and Windows.

I already had Lotus Organiser installed to post a little bit of nostalgia-farming on threads - it's what they do over there.

I thought it might be fun to post a jokey diary entry. I hurriedly made my silly post five minutes after Thom's toot, expecting not to think about this again.

Incorrect, brain

I shut the VM down, then went to get coffee, chuckling to my smart, smug self about my successful nerdy rapid-response. While the kettle boiled, I started pondering - "Wait, if I really did want to make a Mastodon client for Windows 3.11, how would I do it?"

I pondered and dismissed numerous shortcuts, including, but not limited to:

• Fake it with screenshots doctored in MS Paint
• Run an existing DOS Mastodon Client in a Window
• Use the Windows Telnet client to connect insecurely to my laptop running the Linux command-line Mastodon client, Toot
• Set up a proxy through which I could get to a Mastodon web page

I pondered a different way, in which I'd build a very simple proof of concept native Windows client, and leverage the Mastodon API. I'm not proficient in (m)any programming languages, but felt something like Turbo Pascal was time-appropriate and roughly within my capabilities.

Diversion

My mind settled on Borland Delphi, which I'd never used, but looked similar enough for a silly project to Borland Turbo Pascal 7.0 for DOS, which I had. So I set about installing Borland Delphi 1.0 from fifteen (virtual) floppy disks, onto my Windows 3.11 "Workstation" VM.

Thank you, whoever added the change floppy0 option to the QEMU Monitor. That saved a lot of time, and was reduced down to a loop of this fourteen times:

"Please insert disk 2"
CTRL+ALT+2
(qemu) change floppy 0 Disk02.img
CTRL+ALT+1
[ENTER]

During my research for this blog, I found a delightful, nearly decade-old video of David Intersimone ("David I") running Borland Delphi 1 on Windows 3.11. David makes it all look so easy. Watch this to get a moving-pictures-with-sound idea of what I was looking at in my VM.

Once Delphi was installed, I started pondering the network design. But that thought wasn't resident in my head for long, because it was immediately replaced with the reason why I didn't use that Windows 3.11 VM much beyond the original base install.

The networking stack doesn't work. Or at least, it didn't.

That could be a problem.

Retro spelunking

I originally installed the VM by following this guide, which is notable as having additional flourishes like mouse, sound, and SVGA support, as well as TCP/IP networking. Unfortunately I couldn't initially get the network stack working as Windows 3.11 would hang on a black screen after the familiar OS splash image.

Looking back to my silly joke, those 16-bit Windows-based Mastodon dreams quickly turned to dust when I realised I wouldn't get far without an IP address in the VM.

Hopes raised

After some digging in the depths of retro forums, I stumbled on a four year-old repo maintained by Jaap Joris Vens.

Here's a fully configured Windows 3.11 machine with a working internet connection and a load of software, games, and of course Microsoft BOB 🤓

Jaap Joris published this ready-to-go Windows 3.11 hard disk image for QEMU, chock full of games, utilities, and drivers. I thought that perhaps their image was configured differently, and thus worked.

However, after downloading it, I got the same "black screen after splash" as with my image. Other retro enthusiasts had the same issue, and reported the details on this issue, about a year ago.

does not work, black screen.

It works for me and many others. Have you followed the instructions? At which point do you see the black screen?

The key to finding the solution was a comment from Jaap Joris pointing out that the disk image "hasn't changed since it was first committed 3 years ago", implying it must have worked back then, but doesn't now.

Joy of Open Source

I figured that if the original uploader had at least some success when the image was created and uploaded, it is indeed likely QEMU or some other component it uses may have (been) broken in the meantime.

So I went rummaging in the source archives, looking for the most recent release of QEMU, immediately prior to the upload. QEMU 5.2.0 looked like a good candidate, dated 8th December 2020, a solid month before 18th January 2021 when the hda.img file was uploaded.

If you build it, they will run

It didn't take long to compile QEMU 5.2.0 on my ThinkPad Z13 running Ubuntu 24.04.1. It went something like this. I presumed that getting the build dependencies for whatever is the current QEMU version, in the Ubuntu repo today, will get me most of the requirements.

$ sudo apt-get build-dep qemu
$ mkdir qemu
$ cd qemu
$ wget https://download.qemu.org/qemu-5.2.0.tar.xz
$ tar xvf qemu-5.2.0.tar.xz
$ cd qemu-5.2.0
$ ./configure
$ make -j$(nproc)

That was pretty much it. The build ran for a while, and out popped binaries and the other stuff you need to emulate an old OS. I copied the bits required directly to where I already had put Jaap Joris' hda.img and start script.

$ cd build
$ cp qemu-system-i386 efi-rtl8139.rom efi-e1000.rom efi-ne2k_pci.rom kvmvapic.bin vgabios-cirrus.bin vgabios-stdvga.bin vgabios-vmware.bin bios-256k.bin ~/VMs/windows-3.1/

I then tweaked the start script to launch the local home-compiled qemu-system-i386 binary, rather than the one in the path, supplied by the distro:

$ cat start
#!/bin/bash
./qemu-system-i386 -nic user,ipv6=off,model=ne2k_pci -drive format=raw,file=hda.img -vga cirrus -device sb16 -display gtk,zoom-to-fit=on

This worked a treat. You can probably make out in the screenshot below, that I'm using Internet Explorer 5 to visit the GitHub issue which kinda renders when proxied via FrogFind by Action Retro.

Share…

I briefly toyed with the idea of building a deb of this version of QEMU for a few modern Ubuntu releases, and throwing that in a Launchpad PPA then realised I'd need to make sure the name doesn't collide with the packaged QEMU in Ubuntu.

I honestly couldn't be bothered to go through the pain of effectively renaming (forking) QEMU to something like OLDQEMU so as not to damage existing installs. I'm sure someone could do it if they tried, but I suspect it's quite a search and replace, or move the binaries somewhere under /opt. Too much effort for my brain.

I then started building a snap of qemu as oldqemu - which wouldn't require any "real" forking or renaming. The snap could be called oldqemu but still contain qemu-system-i386 which wouldn't clash with any existing binaries of the same name as they'd be self-contained inside the compressed snap, and would be launched as oldqemu.qemu-system-i386.

That would make for one package to maintain rather than one per release of Ubuntu. (Which is, as I am sure everyone is aware, one of the primary advantages of making snaps instead of debs in the first place.)

Anyway, I got stuck with another technical challenge in the time I allowed myself to make the oldqemu snap. I might re-visit it, especially as I could leverage the Launchpad Build farm to make multiple architecture builds for me to share.

…or not

In the meantime, the instructions are above, and also (roughly) in the comment I left on the issue, which has kindly been re-opened.

Now, about that Windows 3.11 Mastodon client…

Last week, the first point release of Ubuntu 24.04 LTS arrived, and upgrades from Ubuntu 22.04 LTS to the newest one officially enabled. However, those upgrades didn't go smoothly for everyone who tried, be it on Ubuntu server or Ubuntu desktop. To prevent further headaches, Canonical has decided to pause upgrades to Ubuntu 24.04 LTS from Ubuntu 22.04 LTS while its developers work out the kinks. Yesterday, the 'noble' release got edited out of the meta-release-lts file (which Ubuntu systems check to detect new versions), preventing users from upgrading to Ubuntu 24.04.1 LTS through officially-supported methods. Folks attempting to upgrade, but suddenly […]

The default wallpaper of Ubuntu 24.10 'Oracular Oriole' (and its official mascot artwork) has been revealed - along with an extra-special 20th anniversary surprise! A visit to the nearest temple mystic wasn't required to predict that the new mascot motif would take centre-stage in the official Ubuntu 24.10 wallpaper. Animal mascots are a recurring feature of the default background since Ubuntu 17.10 'Artful Aardvark'. Default backgrounds follow a set formula purple gradient, some affectation around the edge, and (typically) a line-art illustration of the codename animal in the middle. For the 'Oracular Oriole' we get a geometric rendition of an […]

Continua a conversa com a Rute Correia, fã incondicional de Pusheen, para nos dizer que as consolas estão pela hora da morte; como o Steamdeck é uma bisarma fofinha, graças às possibilidades de personalização do software e do interface aberto - ou até com estojos em malha que tornam tudo mais tchanan. Falámos de XBOX, Vita, como a SEGA Dreamcast estava à frente do seu tempo e ainda lançámos invectivas aos fabricantes para regressarem ao aspecto colorido e translúcido dos anos 90, em vez de fazerem tudo em preto.

The Audacity 3.6 release in July brought some masterful new features with it, plus all-new Compressor and Limiter filters. But not everyone was pleased to lose access to the older version of those, so Audacity's devs have brought 'em back in a point release update to the currently Audacity 3.6 stable series. Those who prefer (or just more used to) the original Limiter, Compressor and Classic filters can access them in Audacity 3.6.2 from the new "Legacy" effects section. They're available to use with new and existing Audacity projects. Audacity 3.6.2 also resolves a sizeable set of bugs, with fixes including: Plus plenty more […]

Ubuntu's new desktop Security Center app is gearing up for its first stable release, along with a background tool called Prompting Client. I first reported on the creation of Security Center earlier this year and it hasn't changed a great deal since then. Underlying code has been improved, and the Flutter UI made to look more like Yaru/GTK, but in terms of what it does, not much! The Snap Store description for the app describes it as "Security Center UI for the desktop", which doesn't say a great deal about the purpose or why a user might want to install […]

Beer, cake and ISO testing amidst rugby and jazz band chaos

On Saturday, the Debian South Africa team got together in Cape Town to celebrate Debian's 31st birthday and to perform ISO testing for the Debian 11.11 and 12.7 point releases.

We ran out of time to organise a fancy printed cake like we had last year, but our improvisation worked out just fine!

We thought that we had allotted plenty of time for all of our activities for the day, and that there would be plenty of time for everything including training, but the day zipped by really fast. We hired a venue at a brewery, which is usually really nice because they have an isolated area with lots of space and a big TV - nice for presentations, demos, etc. But on this day, there was a big rugby match between South Africa and New Zealand, and as it got closer to the game, the place just got louder and louder (especially as a band started practicing and doing sound tests for their performance for that evening) and it turned out our space was also double-booked later in the afternoon, so we had to relocate.

Even amidst all the chaos, we ended up having a very productive day and we even managed to have some fun!

Four people from our local team performed ISO testing for the very first time, and in total we covered 44 test cases locally. Most of the other testers were the usual crowd in the UK, we also did a brief video call with them, but it was dinner time for them so we had to keep it short. Next time we'll probably have some party line open that any tester can also join.

Logo

We went through some more iterations of our local team logo that Tammy has been working on. They're turning out very nice and have been in progress for more than a year, I guess like most things Debian, it will be ready when it's ready!

Debian 11.11 and Debian 12.7 released, and looking ahead towards Debian 13

Both point releases tested just fine and was released later in the evening. I'm very glad that we managed to be useful and reduce total testing time and that we managed to cover all the test cases in the end.

A bunch of things we really wanted to fix by the time Debian 12 launched are now finally fixed in 12.7. There's still a few minor annoyances, but over all, Debian 13 (trixie) is looking even better than Debian 12 was around this time in the release cycle.

Freeze dates for trixie has not yet been announced, I hope that the release team announces those sooner rather than later, also KDE Plasma 6 hasn't yet made its way into unstable, I've seen quite a number of people ask about this online, so hopefully that works out.

And by the way, the desktop artwork submissions for trixie ends in two weeks! More information about that is available on the Debian wiki if you're interested in making a contribution. There are already 4 great proposals.

Debian Local Groups

Organising local events for Debian is probably easier than you think, and Debian does make funding available for events. So, if you want to grow Debian in your area, feel free to join us at #debian-localgroups on the OFTC IRC network, also plumbed on Matrix at #debian-localgroups:matrix.debian.social - where we'll try to answer any questions you might have and guide you through the process!

Oh and btw… South Africa won the Rugby!
