d-u kills plasma-desktop

ruebe99 · 2026/03/20, 10:20:35

Today's d-u unfortunately killed the Plasma desktop; maybe there is a relation to qt6
cheers & good luck

Well, good time to wait a little while.

Im Moment sollte man etwas warten.

Bei mir wird Plasma(X11) nicht gekillt oder anderweitig beeinträchtigt. apt hält bei mir, dem 3er Solver sei Dank, 115 Pakete zurück (und es werden wohl noch viel mehr werden).

Plasma (X11) isn't being terminated or otherwise affected on my system. Thanks to the version 3 solver, apt is holding back 115 packages (and that number is likely to grow even more).

Hier ist die Transition von qt6 auf drei Rechnern mit labwc und hyprland soeben fehlerfrei durchgegangen.

The transition from qt6 to three computers with labwc and hyprland has just gone through without errors.

Current plasma-desktop (= 4:6.5.4-2) still depends on virtual package
qt6-base-private-abi (= 6.9.2) provided by libqt6core6t64 (= 6.9.2+dfsg-4+b1),
but current libqt6core6t64 (= 6.10.2+dfsg-5) provides qt6-base-private-abi (= 6.10.2),
so I would not recommend enforcing the d-u yet.

During an update, "kwin-x11" and "libkwin-x11-6" are to be deleted on my system. I'm waiting until the problem is solved.

a tasksel brought KDE Plasma back again
cheers

@graviton

The wait is over and the qt6 transition should be complete by now.
Can you provide an

$ sudo apt-get update; sudo apt-get -s dist-upgrade

thomv · 2026/03/22, 20:13:47

Bei mir werden (22.03.2026, 20.00) noch 217 Pakete zurückgehalten, darunter plasma-workspace, dolphin, kde-Pakete (kate, ..) und jede Menge libqt6... Pakete.

I will still wait - apt holds still 217 packages.

Teriarch · 2026/03/22, 22:12:29

@thomv

ja, und manchmal liegt der Grund in zurückgehaltenen libuvwt64
Paketen, die durch libxyz Pakete ersetzt werden wollen. Ein

$ sudo apt-get update; sudo apt-get -s dist-upgrade

sollte Klarheit über die zu ersetzenden Pakete verschaffen (ohne etwas
zu verändern).

> I will still wait - apt holds still 217 packages.

Who wants to wait forever?

ruebe99 · 2026/03/22, 22:48:39

you should wait as long as possible. that's my prevered advice.
for my system the status seems to be

What does 'apt -s install kate' want to do?

It will/would "simulate" whatever would happen

. Since there is nothing to do for you ...

For me at least two missing "abi" packages (or virtual packages) are still blocking more than 200 package upgrades.
Triggers for that are "xwaylandvideobridge" and "copyq" (and thus copyq-plugins) here (qt6-base-...-private-abi are (still) missing).

None of them is installed on my system.

xwaylandvideobridge is not part of unstable or testing, so if it is needed, I don't know!?

And copyq, I don't use it, so I removed it.

The upgraded qt6 library (esp. libqt6core6t64) no longer provides virtual package qt6-base-private-abi in version 6.8.2 and 6.9.2
needed by xwaylandvideobridge and copyq, resp. as you can see from

$ apt-cache showpkg qt6-base-private-abi
Package: qt6-base-private-abi
Reverse Provides:
libqt6core6t64 6.10.2+dfsg-6 (= 6.10.2)

So the abi packages are not missing but rather replaced on purpose. But I have good news: The new abi
versions seem to work with old copyq and xwaylandvideobridge, as you can see from

$ dpkg -l|grep -e copyq -e xwaylandvideo -e libqt6core6t64:amd64
ii copyq 13.0.0-1b amd64 Advanced clipboard manager with editing and scripting features
ii copyq-plugins 13.0.0-1b amd64 Plugins for CopyQ
ii xwaylandvideobridge 0.4.0-2+b1b amd64 XWayland Video Bridge for X11 clients
ii libqt6core6t64:amd64 6.10.2+dfsg-6 amd64 Qt 6 core module

A slight modification of the packages can obviously resolve the package management conflicts and
make them continue to work (at least for the moment). There is still hope for copyq to be updated, but as
hendrikL already pointed out, xwaylandvideobridge has been removed.

If these packages are the only obstacle holding you back, I suggest you remove them, upgrade and install
the modified versions thereafter. Let me know, if you are interested and I can provide you with the beta versions
of copyq, copyq-plugins and xwaylandvideobridge (modifications of copyq* will be removed by a later official update).
