you are right, Julian, I am sorry. The behaviour has not changed at all compared to previous ubuntu releases.
In my case there was the dpkg inconsistency, requiring execution of 'dpkg --configure -a' But at the same time there was some dependency problem which required calling 'apt -f install' The latter made 'apt check' error out, but I attributed this to the former. ** Changed in: apt (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1731636 Title: daily unattended upgrade does not recover from interrupted dpkg run (regression) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1731636/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
