This is not a bug in unattended-upgrades, but u-u triggers the problem in many packages which are not able to install/upgrade during a system shutdown.
Helper scripts in init-system-helpers must not start services when maintainer scripts are executed during shutdown and maintainer scripts must use helper scripts and not call systemct and friends directly to start services. Snapd for example calls systemctl start "$unit" in postinst. Thank you for the bug report. I marked it "Confirmed for u-u" to not let it disappear, but u-u is just triggering the issue and it can't be fixed in u-u. -- 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/init-system-helpers/+bug/1778219/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
