I’ve had this issue for a while now, since I thought I could fix it myself. Almost all my programs have lost their icon image, which is not fixable by applying a different icon theme unfortunately. Just installed the Reversal icon pack to test that. My settings are attached here, sorry for the german:

I am assuming this is due to some of the weird behaviour I have had for some days months ago. Gnome would just not load and instead show me an error screen. So I had to uninstall gnome entirely, then reinstall it and that magically fixed it, but my icons were gone.

    Maybe this package isn’t installed either, since I get some sort of error message: Usage: /usr/sbin/update-icon-caches directory [ … ] I tried assigning some directory to it like this: sudo update-icon-caches /usr/share/icons But this didn’t change anything either.

        This is all what shows up. Heres my complete terminal output:
