After recent update Plasma does not come up any more

Hi,

I had so much trouble with updating since switching to manjaro one or two years ago that I delay the upgrade as long as possible until I hope the major bugs have been found. So I believe this was the December update.

on my laptop it went fine but on my desktop plasma does not come up any more. It only shows a few apps that were started from last session but no window manager or task bar.

there are no pacnew or pacsave files.

the journal only shows a generic error, no details.

$ systemctl restart --user plasma-plasmashell
Job for plasma-plasmashell.service failed because the control process exited with error code.

when I try to start β€œkonsole” from a text terminal, I get

$ DISPLAY=:0.0 konsole 
konsole: error while loading shared libraries: libKF6I18nQml.so.6: cannot open shared object file: No such file or directory

I was able to fix this problem by installing ki18n from EXTRA instead of AUR. but now there is the next library missing, while kxmlgui already is the EXTRA version

$ DISPLAY=:0.0 konsole
konsole: symbol lookup error: /usr/lib/libKF6XmlGui.so.6: undefined symbol: _ZN20KAdjustingScrollAreaC1EP7QWidget

is there a way to generally remove some of these AUR installs?
(I really want ksysguard6-git because the stock replacement sucks.)

Recently plasma-desktop crashed on every display standby and on DVD insert/eject, sometimes even killing all dolphin instances. Most of the times I had to manually start plasmashell. but this does not work any more. What exactly should I do?

$ kstart plasmashell
Authorization required, but no authorization protocol specified

qt.qpa.xcb: could not connect to display :0.0
qt.qpa.plugin: From 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to load the Qt xcb platform plugin.
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: minimalegl, wayland, linuxfb, eglfs, wayland-egl, offscreen, minimal, vnc, vkkhrdisplay, xcb.

thnak you very much

The obligatory warning:

Doing this is detrimental to a rolling release distribution such as Manjaro. It’s likely many issues you encounter might be invited by this practice.

If updating bi-monthly, or quarterly is your preference, I’d suggest abandoning Manjaro in favour of a Linux flavour with a point release distribution cycle.

Just something to consider.

Regards.

Probably.

I solved the issue by manually checking any dependency of konsole and replacing the libs with the stock version if necessary.
seems to work again now.

Keep in mind that to mark a topic as solved in the Manjaro forum, you need to click the under the relevent post to mark it as the Solution.

In this instance I have marked your own post as the Solution; even though it’s not standard practice.

I have removed β€œSOLVED” from the title.
