"The Screen locker is broken..." After last updates (13/10/2023)

[GloW]

Just after applying the last updates of today, when I lock the session, a black screen appears indicating that the screen locker is broken.

usr/lib64/kscreenlocker_greet --testing
kf.kirigami: Failed to find a Kirigami platform plugin
Cannot mix incompatible Qt library (5.15.10) with this library (5.15.11)

Could you help me?

Welcome to the forum!

Have you rebooted after the update?

You may also want to read this HowTo.

[HowTo] Updating Manjaro as safely as possible

The golden rule — which nobody follows, of course — when using a rolling-release distribution…: Always apply the bundled updates by way of the command line in a tty while completely logged out of your graphical environment, so that no shared libraries will be in use that will be overwritten by the update process. The safest way even would be to cleanly reboot your system first before applying any updates, and to then switch to a tty and run the update process from there without logging into…

Thanks Aragorn.
Yes, sure.

And I have just found the problem:
replace qt5-virtualkeyboard-bigscreen with qt5-virtualkeyboard.

PD: Thanks for the HowTo. I will read and follow it the next time.
