Hi everyone, I ran apt full-upgrade last month and accidentally deleted a couple packages that weren’t supposed to be removed, due to me not paying enough attention. I could recover most of the system just fine, since most of the missing features and related packages were obvious to me. However, I still couldn’t figure out why transparency is not working on KDE, both in Wayland and X. I suspected it could be a missing compositor, but libwayland and libqt6waylandcompositor6 (and related packages) are all installed (and that wouldn’t explain why it isn’t also working on X).
I have attached a screenshot to illustrate what I mean.
I would appreciate if anyone could help me figure out what package might be missing that is causing this issue. Thanks in advance!
EDIT: Thank you so much everyone! I finally solved my problem. I just had to replace libqt5quick5-gles by libqt5quick5 (non gles version).
Commandline: apt install libqt5quick5
Install: libqt5quick5:amd64 (5.15.10+dfsg-2+b2)
Remove: libqt5quick5-gles:amd64 (5.15.10+dfsg-2+b2)
Most people don’t really get out their way to set up backup manually. Either system should try really hard to avoid corruption or implement a recovery system. Ideally both.
Well, the Linux world is moving towards btrfs and zero-setup automatic snapshots. Those would have made it trivial to rollback a broken update like that. Unfortunaly, it’s still going to take a few years before Debian makes the move…
Debian is as traditional as it gets, change comes slooowly. I don’t see why it’s still so popular
You don’t need to get out of your way. You can, for example, just tar --one-file-system, clonezilla or rsync or maybe even drag and drop copy all your important file systems on a USB HD, USB stick or cloud storage that you then check and unplug/unmount.
This is very easy and can run in the background while you do some other stuff. Even if the backup isn’t good and for example doesn’t have proper permissions, because you drag and drop copied, it will have the info required to reinstall and restore the exact system you had at the time of the backup.
