When snapd is not in a good state, do-release-upgrade systematically fails on upgrade from eoan (19.10) to fossa (20.04).
The only messages displayed on the terminal by do-release-upgrade are : Restoring original system state Aborting Before using snapd, I think that do-release-upgrade must test if snapd is in a good state, and display an explicit error message if not. For me, the successful workaround was to uninstall then reinstall the snapd package. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1849669 Title: do-release-upgrade (19.04 -> 19.10) aborts when snapd is disabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1849669/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
