KDE/Plasma 5.23 “25th Anniversary Edition” for Debian

by ·

In the last week, KDE released version 5.23 – 25th Anniversary Edition – of the Plasma desktop with the usual long list of updates and improvements. This release celebrates 25 years of KDE, and Plasma 5.23.0 was released right on the day 25 years ago Matthias Ettrich sent an email to the de.comp.os.linux.misc newsgroup explaining a project he was working on. And Plasma 5.23 (with the bug fix 5.23.1) is now available for all Debian releases. (And don’t forget KDE Gears/Apps 21.08!)

As usual, I am providing packages via my OBS builds. If you have used my packages till now, then you only need to change the plasma522 line to read plasma523. To give full details, I repeat (and update) instructions for all here: First of all, you need to add my OBS key say in /etc/apt/trusted.gpg.d/obs-npreining.asc and add a file /etc/apt/sources.lists.d/obs-npreining-kde.list, containing the following lines, replacing the DISTRIBUTION part with one of Debian_11 (for Bullseye), Debian_Testing, or Debian_Unstable:

deb https://download.opensuse.org/repositories/home:/npreining:/debian-kde:/other-deps/DISTRIBUTION/ ./
deb https://download.opensuse.org/repositories/home:/npreining:/debian-kde:/frameworks/DISTRIBUTION/ ./
deb https://download.opensuse.org/repositories/home:/npreining:/debian-kde:/plasma523/DISTRIBUTION/ ./
deb https://download.opensuse.org/repositories/home:/npreining:/debian-kde:/apps2108/DISTRIBUTION/ ./
deb https://download.opensuse.org/repositories/home:/npreining:/debian-kde:/other/DISTRIBUTION/ ./

The sharp eye might have detected also the apps2108 line, yes the KDE Gear suite of packages hgas been updated to 21.08 some time ago and is also available in my OBS builds (and in Debian/experimental).

Uploads to Debian

Plasma 5.23.0 has been uploaded to Debian, and is currently in transition to testing. Due to incorrect/insufficient Break/Depends, currently Debian/testing with the official packages for Plasma are broken. And as it looks this situation will continue for considerable time, considering that kwin is blocked by mesa, which in turn is blocked by llvm-toolchain-12, which has quite some RC bugs preventing it from transitioning. What a bad coincidence.

KDE Gears 21.08 are all in Debian Unstable and Testing, so the repositories here are mostly for users of Debian Bullseye (stable).

Krita beta

Krita has released the second beta of Krita 5.0, and this is available from the krita-beta repository, but only for amd64 architectures. Just add

deb https://download.opensuse.org/repositories/home:/npreining:/debian-kde:/krita-beta/DISTRIBUTION/ ./

Enjoy the new Plasma!

      Hi. Great work. How long and frequent do you plan to update this repo for Plasma 5.23 on Bullseye? Do you add minor point releases? I am interested and evaluating to use your repo for the Neptune Distro which is based upon Debian to provide the newer Plasma version to our users.

    Thanks, Norbert, for all your work on packaging KDE! Gone are the days where it takes many months from a KDE release to a first upload into Debian. 🙂

    > Due to incorrect/insufficient Break/Depends, currently Debian/testing with the official packages for Plasma are broken.

    This had me worried since I was unsure what I have to do to avoid breaking my system (other than just not installing any updates), but it seems there is an easy workaround. So for anyone who wants to know more, here are the details: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=996761

    Thanks for the update. Overall it works quite good, I have just two smaller issues with my setup with Nvidia drivers and the desktop effects. First, the “blur” effect, which leads to artefacts on the screen, for example if you let the Yakuake screen slide in and out. And second with the “magic lamp” effect for minimizing windows which does not work at all. I disabled the two effects and the rest seems to be ok. Thanks for your work.

      Thanks Thomas, but the discussion you linked is about the cube effect. I don´t think it´s related. I also use a whole bunch of virtual desktops and activities but I use the “raster” effect instead of the cube. Sad nevertheless that features are being cut down for those who are used to use them.

    Some recent problem with upgrading:

    The following packages have unmet dependencies:
    kimageformat-plugins : Depends: libavif9 (>= 0.8.4) but it is not installable

    Currently testing / unstable have libavif12, not llibavif9.

        Hi Norbert,

        First up, even if you’ve heard it many times over, thanks for doing so much and such fabulous work. I hope you are taking it easy and kicking back from time to time too.

        The size-mismatch with latte dock still persists. I am on Debian 11 and can’t seem to make it work. Any tips about what I can do?

        Cheers

    Another weird issue. Kdenlive searches by default for the wrong mlt path /usr/share/mlt instead of /usr/share/mlt-7 and I only could bring it to work with providong that path via command line.
    With that I get kdenlive started but it does not find any HD or FullHD profiles only some 4k DCI ones. Not sure whats wrong here and if that can be addressed with an update of some sorts

      Hmm, this is strange. I cannot see any of this on my system. I not even know what mlt is doing, but in the settings of kdenlive there the “MLT Profiles folder” and it points to “/usr/share/mlt-7/profiles”, and I see a lot of 4k etc profiles.

    Hi, Norbert.
    I updated my debian testing with KDE 5.21 today (october 25tj) and now my desktop no longer loads. It seems there are a several KDE 5.23 packages installed mixed with 5.21, and as you said, fixes will take long.
    My question is, can I use your repos to install 5.23 succesfully? Or at least go back to 5.21?
    What command should I type to update all Kde packages?
    Thank you!

      Hi
      you have two options, one is to downgrade libkdecoration5v5, the solution that brings you to 5.21 and stays completely in Debian.
      The other option is to activate my repositories and install the missing 5.23 packages from there.
      Both are fine.

        Thanks. It loaded correctly now, but I’m seeing some differences: Bluetooth is enabled (when I had it disabled), I cannot connect to any Wifi anymore (journalxtl says: “no secrets: No agents were availablew for this request. Failed for conncetion ‘{SSID_NAME}'”

        I see 8-9 packages installed from 5.23, like:
        kde-config-gtk-style,
        kde-config-sddm,
        kde-config-updates,
        kde-style-breeze,
        kde-style-oxygen-qt5,
        libkdecorations2private9
        and polkit-kde-agent-1

        You suggest to downgrade those packages to 5.21 or install kde 5.23 form your repos?

        This is the first time using that kind of DEB source URL. If I wanted to APT-pinning, how would I do that with your repo:
        “deb https://download.opensuse.org/repositories/home:/npreining:/debian-kde:/plasma523/Debian_Testing/ ./”
        What’s its name in order to use it in “/etc/apt/preferences”?

          Ok, i learned a bit more about apt pinning and I could pin according to “origin URL” with:

          Package: *
          Pin: origin download.opensuse.org
          Pin-Priority: 700

          Now I have KDE 5.23.1 from your repos and Wifi worked again.

    Hi Norbert!

    I was just installing Debian with KDE and noticed that it still defaults to maui theme for sddm instead of breeze which looks much nicer and fits Plasma defaults.

    I even filed a bug about it a while ago: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=949340

    Can you please help fixing it. Not a deal breaker but would improve Debian KDE experience.

    KDE Plasma 5.23.3 really works great here on wayland, but there’s one thing missing: screen sharing/recording. I’ve installed all the needed packages (pipewire, xdg-desktop-portal and xdg-desktop-portal-kde), everything is running, but OBS and Chrome aren’t able to access screens or windows using pipewire.

    In /var/log/user.log there are entries like this:
    Nov 13 18:09:14 thinkpad org.freedesktop.impl.portal.desktop.kde[2808]: xdp-kde-screencast: zkde_screencast_unstable_v1 does not seem to be available

    As far as I’ve seen, the needed stuff should have been included by this merge request https://invent.kde.org/libraries/plasma-wayland-protocols/-/merge_requests/1/

    I’ve just received the framework updates (5:5.87.0-1~np2 -> 5:5.88.0-1~np1), on bullseye, now the infocenter (kinfocenter) and the settings (systemsettings5) crash on startup with segmentation fault. The system monitor (plasma-systemmonitor) when you try to show the about information.
    X11 or wayland makes no difference.

    Is it a known problem?

        This can happen, and adding your repository is our own risk. Thanks a lot for doing this great job (not ironic, I’ve packaged 12 years for openSUSE/packman, I know how much work is needed to keep so many packages up to date). I’m sure it will be fixed soon and inbetween I’ll downgrade the package to 5.87.0 on my working computer (always good to have a computer with cachted packages ;-)) and disable the repository.
        For testing my old Notebook will keep in think with the repo.

        I haven’t tested all KCMs, but at least kcm_landingpage, kcm_colors and kcm_fonts are crashing during their QML UI initialization (both when opening through systemsettings5 or via kcmshell5), others like kcm_lookandfeel or kcm_style at least load fine (haven’t tested changing any settings though). The crashing ones all crash with the same backtrace deep in the bowels of libQt5Qml when dereferencing a NULL pointer. Rebuilding plasma-workspace (because the crashing KCMs are from this package) and systemsettings (because it’s the only thing not KF5 or Qt5 in the backtrace) against the updated KF5 libraries didn’t change anything, so I don’t think this is due to an incomplete update but rather a genuine regression somewhere in KF5.

        The exact same crash seems to happen on Debian unstable too BTW: https://bugs.kde.org/show_bug.cgi?id=445453

        Update to my other comment: I was able narrow it down to qml-module-org-kde-qqc2desktopstyle. If I downgrade that package to the previous version (5.87.0-1~np2) then the crashing kcm modules start working again.

    Just a heads up: the latest framework update 5.88 breaks the breeze-dark icon theme due to a bug in the cmake setup that was introduced upstream two weeks ago. I’ve already reported it: https://bugs.kde.org/show_bug.cgi?id=445489

    To fix it for the Debian package until it gets fixed upstream you could add a local patch reverting the two commits mentioned in the bug report that caused the bug.

      Thanks for the pointer, but something is still strange. The latest set of packages (1~np2) reverts the two commits, but the icons on my desktop now look very different. Need to investigate.

        Yeah, I think the commit 1b92cfc450f6ab6b72ed9ef69c052e4624e5a040 (and maybe bc18bf8e28e1110d752f94412f2314c7b57f9fdb) needs to be reverted too. The guy making those changes doesn’t seem to have understood how icon theme inheritance works, in particular that if an icon doesn’t exist in the current theme in the requested size then it first looks for a different size of the icon in the same theme, and only if that still didn’t find anything is the parent theme checked. So by removing those “duplicates” he actually broke all icons where only certain sizes had dark-mode specific versions, and then made things even worse with the later attempt to fix it.

    Unfortunately, some other KF v5.88.0 packages depend on newer kirigami2.

    Problems seems to be qml-module-org-kde-kirigami2 package.
    I was able to use the older version together with the newer libkf5kirigami2-5 by manually copying files/dirs.

    I cannot answer to all comments here, but 5.88.0-1~np2 should fix all the problems. Sorry for the inconveniences.

    I have them running on my computer and kinfocenter and systemsettings5 runs without any problems.

    qml-module-org-kde-qqc2desktopstyle in version 5.88.0-1~np3 should fix the problem. There were missing dependencies on qml-module-org-kde-sonnet. That also explained why it worked on one of my system where the package was installed.

    HI,
    I am trying to install Kde 5.23 but I cant select it from the login screen, the only thing that shows up is Gnome.

    I had KDE 5.22 working fine, but after a system update it broke. I uninstalled Plasma then reinstalled with Debians repos, worked fine. As soon as I tried 5.23, same problem, no option to select it from the login screen.

So I cannot help more than advise you to read the log files of the display manager and see if there is something there. Also, do you have all the plasma related packages installed.

        I installed minimal version of plasma. this is the command that I used to install

        sudo apt install kde-plasma-desktop plasma-nm

        after the install I updated the repositories, issued the update and upgrade commands, did a reboot, and when I logged in to plasma everything still fine. then it said I hade more udates so I installed them and that is when it broke. no more plasma.

        if I do the install plasma command, this is the errors I get.

        sudo apt install kde-plasma-desktop plasma-nm

      I have a sid (unstable) Debian and you have installed a Debian stable. Our systems are not exactly comparable.
      Please report the results of
      apt install plasma-workspace
      apt install kinfocenter
      Could be unresolved dependencies, because of
      “plasma-workspace (>= 4:5.23~) but it is not installable”,

      OTOH those packages are shown by the policy command.

    I am trying to use these packages with bullseye, but I cannot install plasma-workspace because it depends on libqalculate22. This was also mentioned in other comments, but I do not understand the solutions mentioned there. This package is not available at all in bullseye and also not after adding the repositories from here:

      No, in fact it is currently broken because the build of libqalculate was deactivated. I have kicked of a rebuild and the OBS servers are crunching at it. Hopefully in short time (few hours) the package should be available, and with that update should be possible.

    Hello! After updating the KDE Plasma packages to version 5.23.3, I ran into the problem again – MTP does not work in Dolphin. I have libmtp packages installed, KIO is also installed, but the error still pops up: “File or folder udi =/org/kde/solid/udev/sys/devices/pci0000: 00/0000:00:14.0/usb1/1-2 does not exist “. That being said, everything works fine on Arch Linux and OpenSUSE. Debian is installed via netinstall, Plasma-Desktop package is manually installed. Maybe I did something wrong?

    I am attaching a screenshot (in Russian, but I translated the error in the message): https://ibb.co/kDDkwg4

    I also noticed that for some unknown reason, KDE Plasma on Debian is much slower than Arch and OpenSUSE. Could you tell me why this is so?

    Thanks in advance! =)

      Not sure what this might be, maybe some permissions are not correct? Or you are not member of the correct groups? I really don’t know. I just plugged in a MTP device and it had a UDI very similar to yours, and worked without a problem.

      Concerning the “slow”, that is even harder to reason about: What is slower? Do you have hardware acceleration turned on? Is the compositor turned on? (See above comments) … There shouldn’t be any noticable speed difference when the hardware is properly set up.

        I have no problem with hardware acceleration. Rendering is included in OpenGL 3.1, but everything is the same in 2.0, and the operating system is installed on an SSD. So, for example, Dolphin starts up in almost 1.5-2 seconds, while in OpenSUSE and Arch it starts almost instantly, and KDE Plasma runs more smoothly there than in Debian (and this is in an X11 session). Perhaps I’m wrong, but it seems to me that Debian simply does not cache the launch of the most frequently used programs and reloads the libraries every time (again, perhaps I do not understand something and know little about it)

        But I don’t know about MTP. USB devices such as thumb drives are working properly. KDE Connect, like Bluetooth, works just as well. There was a similar error with MTP back in version 5.22, and it was fixed by Dolphin update, but this time I even ran dpkg-reconfigure dolphin (also kio), but it did not help

    Hi Norbert!
    Thanks for you great work!

    It looks like this issue https://bugs.kde.org/show_bug.cgi?id=445518 is present in the breeze-icon-theme 4:5.88.0-1 package from the Debian repository.

    Replacing only one breeze-icon-theme package with version 4:5.88.0-1~np2 from your repository solves this problem.

    Btw, regarding ksysguard in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=996737

    Unfortunately Plasma System monitor isn’t a good replacement yet due to maintainers not allowing selecting arbitrary sensors for CPU and GPU in it.

    See: https://bugs.kde.org/show_bug.cgi?id=438318

    Can you please help restore ksysguard in Debian repos? Until KDE Plasma System Monitor developers will change their approach, ksysguard is the only sensible option if you need flexible sensors monitoring.

    Thanks!

      Sorry, not going to happen until upstream authors provide updated packages of ksysguard that works with curretn libksysguard. There was some movement around 5.21 but I haven’t seen any further updates, so it might not happen at all. Maybe you could help them getting ksysguard working with current libksysguard?

        Alright. But it might more productive for me to look into how to patch Plasma system monitor to prevent that artificial sensor filtering. That would be especially useful if upstream developers will decide not to cooperate and keep filtering things going forward.

      What version do you have installed and what are you going to install?
      There are some changes concerning hires support, and it is not clear what will be the correct layout for now.
      If you want to get the latest version, then do `sudo dpkg –purge –force-depends breeze-icon-theme` followed by `sudo apt install breeze-icon-theme`, that should do it.

    Just recently noticed that you posted apps2112, but only because I once in a while check this the repo.

    Can you please make some kind of seamless way of pulling latest plasma, frameworks and apps? Something like a symlink “plasma-current”, “frameworks-current” and “apps-current”, that would point to the latest compatible combinations? Then there won’t be a need to modify apt sources when you post an update and just bump your symlinks.

    Using a virtual machine with a fresh installation + your repo did not find any problem. So, I tried to solve it using tasksel, first uninstalling task-kde-desktop and after reinstalling it, and it works.
