Sddm borked after update

After updating Garuda will not run programs and power controls are inoperable. Forced power cycle resulted in a default sddm theme that shows this message:

The current theme cannot be loaded due to the errors below, please select another theme.

file:///usr/share/sddm/themes/NetLogin/Main.qml:9:1: plugin cannot be loaded for module "org.kde.plasma.core": Cannot load library /usr/lib/qt/qml/org/kde/plasma/core/ ( cannot open shared object file: No such file or directory)

Logging in only flashes the screen and resets the prompt for credentials.

After posting in this thread I restored the pre update snapshot then installed and applied the Terminal Style Login sddm theme before updating again. The results were the same inability to run anything or access the power menu before forcing shutdown. The new sddm theme appears to load and the error message is gone, but actually logging in is still just flashing the screen and resetting the prompt so I've restored the pre snapshot again.

Did you change the standard login theme to TerminalStyleLogin?
And now there is this problem?

No, I had changed it to the "NetLogin" theme referenced by the error message a long time ago and haven't had any issues with it until now. I changed to the "Terminal Style Login" today in an unsuccessful attempt to fix the issue.

How about the standard theme?
My KDE machines boot without problems.


Search in forum about, latte dock is out of date.

Tbh I don't even remember what the standard sddm theme is for kde . . .

So according to a comment on the AUR page for libplist-git "libplist has had a soname bump recently, which means all dependents need to be rebuilt against the new library.". Does this mean I'm stuck being unable to update until all of the affected kde pkgs are rebuilt, or is this something I can/should do myself?

Posting a link may helpful (always).

Package Base: libplist-git
Description: A library to handle Apple Property List format whereas it's binary or XML

You have to rebuild the packages if it is not done upstream. I would ask there. Because I am not sure. :slight_smile:
