This affects Bionic reported on (LP: #1796376). It was only fixed for Cosmic.
I have tested w/ a test package of 'u-u' and it fixes the problem so far, but I have asked impacted user to give it a try as well for double- confirmation. If it fixes the problem, I'll SRU it for Bionic. - Eric ** Also affects: apt (Ubuntu Bionic) Importance: Undecided Status: New ** Also affects: unattended-upgrades (Ubuntu Bionic) Importance: Undecided Status: New ** Also affects: init-system-helpers (Ubuntu Bionic) Importance: Undecided Status: New ** Also affects: snapd (Ubuntu Bionic) Importance: Undecided Status: New ** Changed in: unattended-upgrades (Ubuntu Bionic) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1778219 Title: unattended-upgrades hangs on shutdown, leaves system in a broken state To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1778219/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
