Configure Digital Clock Not Working

,

Fedora 44 KDE Workstation

When I open ‘Configure Digital Clock’ in the Panel, an empty, transparent window is opened. Any idea what’s wrong?

It’s working for me, so it’s not a general problem I assume.

Have a look at the user journal and see if you have any errors there when you try to configure the clock.

Run this in a terminal:

journalctl --user ---follow

Now try to configure the clock.

Do you see any interesting logs?

flatpak and dnf are both up to date. Don’t know how to correct this error.

Is the digital clock the standard KDE one or a third party clock?
If it’s KDE’s then this is an unexpected error.
If it’s a third party clock then they you need an update from them.

It is the standard clock provided by KDE Plasma.

I ran this command yesterday:

sudo dnf reinstall qt6*

After restarting this morning, I find the Digital Clock Settings app appears to be working properly.

No idea how this appears to have fixed the issue…

It appears that some of the files in /usr have been damaged or deleted.
Is it possible you ran a command that might have done that?
It is also possible from you have a hardware issue.
Any other signs of problems?

The only explanation that seems plausible to me is that I recently upgraded from F42 to F44.
