Kscreenlocker broken after qt5 5.15.3 updates on experimental

Lock screen is broken. Says:

In order to unlock switch to a virtual terminal(Ctrl+Alt+F2), login and execute the command loginctl unlock-session 2. Afterwards switch back to the running session (Ctrl+Alt+F1)

Tried: resetting lock screen params and image in settings GUI; solution from here; reinstalling kscreenlocker. Nothing helps so far.

Here’s latest attempt’s log from journalctl:

I guess there’s something wrong with installed qt packages…

Yep. You are right. What is the output of cat /var/log/pacman.log | grep qt5?


Is any of these stuff installed from the AUR? If yes then rebuild them. Also try resetting your themes and stuff to verify if it’s the themes causing the issue or not.

Well, there’s a lot of stuff, I’ll include only ones which contains 5.15.3:

Here’s the output you’ve requested: https://0x0.st/oP5x.txt

I tried resetting theme to default breath/breeze, but that didn’t help.

I’ve managed to fix the issue by reinstalling qt with pamac install qt5 and all proposed plasma packages.
