Hi, thank you to report the bug and your help to make Ubuntu better even when you hate it.
I see that your system has the file in question in a modified state: modified: usr/share/doc/libcgmanager0/changelog.Debian.gz usr/share/doc/libcgmanager0/copyright The system can't know why that is, so it refuses to just overwrite them on upgrade as you might have had a valid reason for it. Aventually you can check for the full package status via dpkg --verify libcgmanager0 It will report you all the files not matching the expected checksums. If you want to throw away local changes you can rm them and the next upgrade once your start it again should succeed (others prefer to remove+purge and reinstall, but that depends on you). ** Changed in: cgmanager (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1646869 Title: package libcgmanager0 0.24-0ubuntu7.5 [modified: usr/share/doc/libcgmanager0/changelog.Debian.gz usr/share/doc/libcgmanager0/copyright] failed to install/upgrade: trying to overwrite shared '/usr/share/doc/libcgmanager0/copyright', which is different from other instances of package libcgmanager0:i386 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cgmanager/+bug/1646869/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
