KDE Gear is our release service for many apps such as mail and calendaring supremo Kontact, geographers dream Marble, social media influencing Kdenlive and dozens of others. KDE needs you to test that your favourite feature has been added and your worst bug has been squished.

You can do this with KDE neon Testing edition, built from the Git branches which get used to make releases from. You can download the ISO and try it on spare hardware or on a virtual machine to test them out.

But maybe you don’t want the faff of installing a distro. Containers give an easier way to test thanks to Distrobox.

Install Distrobox on your normal computer. Make sure Docker or podman are working.

Download the container with

distrobox create -i invent-registry.kde.org/neon/docker-images/plasma:testing-all

Then start it with
distrobox enter all-testing
And voila it will mount the necessary bits to get Wayland connections working and keep your home directory available and you can run say

kontact

and test the beta for the mail app.

We have just switched on the upgrade for KDE neon to rebase on Ubuntu 24.04 LTS.

We do this every two years and the 22.04 LTS base was getting increasingly crusty with old Pipewire causing problems and packages like Krita not compiling at all.

Follow the Noble Upgrade instructions or just click the notification that should appear soon.

Back from the fun of Akademy in Würzburg we can now get to the important task of testing Plasma 6.2 beta. It’s now in KDE neon testing edition which we build from the Git branches which will be used to make the 6.2 final release in 2.5 weeks time. Grab it now or if you don’t have a machine to install it on you can try the Docker images using the simple command `neondocker -p -e testing`.

KDE Akademy is meeting this week in Würzburg.

We just had a BoF session where we discussed..

• The current progress to rebasing on Ubuntu 24.04
• The current state of KDE neon Core our amazing forthcoming Snap based distro
• Fixing up broken and bitrotting infrastructure
• Moving to KDE invent
• Issues with Plasma 6 upgrades and looking at integrating more QA tests
• How the proposed KDE Linux^TM distro fits into the mix

Here at KDE neon tower we have been busy rebasing our KDE software builds from Ubuntu 22.04 (jammy) to Ubuntu 24.04 (noble). This always takes longer than you’d think, mostly because it’s a moving target so we also have to keep updating the incoming releases from Plasma, Frameworks, Gear and even Calligra. We had a couple of delays when Jonathan caught Covid (4 years after it was worth sympathy to do so) and then the build server had issues and needed itself rebuilding. But the package archives are there and the Docker images are there and today the first ISO got built which boots successfully. Next steps are making sure all the software is up to date and getting the upgrade solid. Be with you soon!

The new Ubuntu LTS was released in April, congratulations to all involved with that. I know Scarlett worked hard to get Kubuntu back into shape so do if that a try if you want a stable Plasma 5 desktop.

In the KDE neon project we don’t like to sit still for long so we are now building all our KDE packages on Ubuntu Noble, versioned 24.04. This always takes longer than it feels like it should, mostly because it’s a moving target to keep everything compiled as more KDE software gets released, so no promises on when it’ll be ready but we’ll try to be fast because the old Ubuntu base of jammy (22.04) is showing its age with projects like Krita no longer able to compile there.

So far the main issues are all the changes needed for 64-bit time_t to fix the y2k38 problem, we know you wouldn’t want your clocks to zero out in 2038.

The goal of KDE neon is to build all KDE’s software on a stable Ubuntu LTS base, we do it in an automated way and for the User edition have automated QA to deploy rapidly but safely. For the KDE 6 Megarelease there was a lot of updates and the system didn’t work as well as it ought, not all the update issues could be tested and this broke some the operating system on some people’s computer which is a horrible experience that should not happen.

What happened?

We were testing KF6, Plasma 6 and KDE Gear 24.04 in our unstable and testing repos for some time before the release. A week ahead of release we were building it in our User repo and testing upgrades. Jonathan, as release manager for both the MegaRelease and neon, travelled to Malaga to do an in person joint release with Paul from promo, this helped the coordinated release but lost some testing time. Some package transitions happened during the pre-release week which made the updates more complex than they had to be and meant extra work (for better end result in theory). Once the MegaRelease sources were published on Thursday the testing of Neon was ongoing and many later fixes were made to make for a successful upgrade on the tests. Neon’s KF6/Plasma6/KDE Gear 24.02 packages were published later on Thursday and Jonathan drove home, alas due to bad weather there was no internet available on the ferry limiting later fixes.

Although the semi automated upgrade tests passed this didn’t cover all cases and some people had incomplete upgrades due to packaging transitions being incomplete. This was fixed over the next day or two and also an update to the installer Calamares was brought in which turned out to have a bug with the final install setup so although upgrades now worked the ISO installs were broken. Quite horrible.

On the Monday Jonathan fixed some more upgrade issues and Calamares so the neon end of things was fixed but there remain other problems with KF6 and Plasma 6 which affect all distros and many of these have since been fixed and some are ongoing, many caused by the switch to Wayland or Akonadi switching to sqlite.

Issues?

There wasn’t one big problem that caught everyone. There was lots of small but significant problems which caught many people.

• KMyMoney package issues – needed a rebuild which we did after release
• Ocean sound theme not installed – new package which was added after release
• Palapeli packages in wrong location – an incomplete change that was made during the transition
• Video and pdf thumbnailers broken – these packages needed added to the main install
• KOrganizer had invalid dependency – that needed removed
• xwaylandvideobridge error on shared library – needed a rebuild
• libzxing needs soname bump – that transition needed completed
• akonadi not working on upgrade – for some reason some users had to manually reinstall the mysql akonadi backend
• Calamares install fails to happen – a bug from Calamares that was initially avoided but later included in our ISO
• OEM mode no longer worked – this affects Slimbook systems and some parts just needed ported to Plasma 6, ideally it would be code which was in Calamares and not in Neon

NVidia users had a number of issues often caused by the switch to Wayland. Most users can switch back to X11 to get it working but that is hardly a user friendly setup.

This is just a small sample, there were more similar issues.

Review

Neon is a small team, Jonathan working on it (alongside release duties for Plasma and Frameworks) from Blue Systems and top volunteer helper Carlos with occasionally Harald and others helping out.

We had a review with KDE’s QA star Nate of what happened and why and mitigations and we also had two open calls with neon community members where they gave their feedback.

Ponderings

The Plasma 6 and KF6 upgrades in neon were too fragile and caused too much pain for many of our users.

There wasn’t one single problem and many people had a perfectly good experience doing the upgrade but too many people were caught with problems which will be painful when you are just wanting to have a useful Linux system.

Conclusions

Our constantly rolling release model and small team means we can’t guarantee total stability so we will stop using terms like “rock solid base” on our website and emphasise the new-ness factor.

When doing big updates test and if travelling bring in other people to do testing and fixes.

We can’t support NVidia hardware as we don’t have the skills, time, hardware or access to source to fix it.

Switching to Wayland was a choice of Plasma and after a decade in development a necessary choice but we should be aware of issues there and communicate those.

Get more QA on ISO images, currently we don’t have any prior to release which is going to lead to problems.

Consider if we can to upgrade QA on older snapshots as well as the current one.

Consider how to do more QA on KDE PIM apps.

Thanks to all our lovely users for staying with us, sorry to those who we let down and those who have left us. Thanks to our community for staying supporting of each other and us as developers. Of course there’s plenty of alternatives if you want a slower release cycle (Kubuntu have just made a new LTS with Plasma 5) but if you want the freshest software from KDE then neon continues to be a great place to get it.

We’re a few weeks after the KDE 6 Megarelease and while many people have it working well there were too many problems in KDE neon’s rollout.

We’ll be hosting two Open Door Chats on KDE meet tomorrow (Tue 16 April) where users can talk to the developers to talk about any problems you had.

https://meet.kde.org/b/jon-0yw-xqi-sk6 The access code will be posted on the KDE neon Telegram group and Matrix room or e-mail jr@jriddell.org for it

Chats at 09:00 UTC (10:00 BST, 11:00 CEST) and 19:00 UTC (20:00 BST, 21:00 CEST) Tue 16 April 2024

Today KDE has made its biggest release ever, never before in the 25 year history of the project have we announced so many new products at the same time but it brings the newly refreshed base to keep our software foundation strong.

KDE neon User edition has now been updated with KDE Frameworks 6, Plasma 6 and all the apps from KDE Gear 24.02. You can upgrade through Discover or grab the newest installable ISO build.

If you just want to give it a try then give the Docker images a go.

Many thanks to Carlos, Harald and Jonathan for making this Neon release, to the 100s of KDE developers for writing the software and to Augustin and Paul for hosting the release sprint in Malaga.

It’s high tension in Neon towers this week as the distro packagers have been given access to the source tars for Plasma 6 along with Frameworks 6 and KDE Gear 24.02. This means our cloud of build servers have been powered up to compile them into .deb packages which go into our Apt archive. In principle we already have the packaging working in Unstable and Testing edition so it should be a case of just doing a fresh build in User edition but it involves several hundred source builds all done for the three editions and for libraries and plugins (such as KIO Workers) many of them twice over, once for Qt 6 and once for Qt 5 builds. So lots of bits which need aligned. Frameworks completed yesterday morning and this morning it looks like all of Plasma is built. The KDE Gear apps are churning away now. We’ll then need to tests it all including many configurations of upgrade to make sure it doesn’t break your laptops. The releases are due on Wednesday and with any luck we will have Neon builds available very shortly after, but of course we’ll wait until it’s ready if that’s what we have to do. It’ll be just a normal upgrade available to Discover but of course with a large number of packages to download. Who’s excited?
