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?


Time for “aptitude”
Can also endorse
aptitude, but hopefully OP already has it installed prior to this issue. May have to manually install usingdpkgif not. Whenever I run into issues like this,aptitudesolves it 95% of the time, makes regularaptlook like a baby helplessly crying.That fixed it, thank you so much!
Somehow I can’t even install aptitude trough dpkg because it says that the filesystem is read-only
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
