I'm having the exact same issue in Pop!_OS 20.04 LTS I fixed it once by doing:
sudo dpkg --force depends -P libglib2.0-0:i386 But then the next time I did an update the issue came back again. This definitely seems like an upstream problem as it affects multiple Ubuntu derived distros. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to glib2.0 in Ubuntu. https://bugs.launchpad.net/bugs/1962780 Title: During install "error processing package libglib2.0-0:i386" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glib2.0/+bug/1962780/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
