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
Sounds like your hard drive may be dying.
No, I just figured it out. I had to enable a systemd service to test Cosmic. I have disabled it and now dpkg works and I manually installed Aptitude with its dependencies.
I tried to do an upgrade with Aptitude but it won’t do anything. I’ll look into it more later
