I’ve been trying the COSMIC store and it looks like it killed my apt somehow. Apt says that there is a version mismatch between some libc6 packages, but I checked with dpkg and it all looks correct.

Apt says that I’ve a newer version of some packages but that is not true. Is there any way to fix this?
EDIT: Fixed formatting


I once tried to backport a package on Debian stable because I really wanted to run xwayland-satellite on Niri and I ended up breaking the system. I was using stable debian as-is since then, before switching to Arch.
