I could not agree more with Robert Jansen, as I also think the problem is caused by the systemd plague. Steps to reproduce on a Thinkpad X1 Carbon 4th gen:
1) Turn on; shutdown -h now => no problem; 2) Turn on; sleep (e.g. close lid); wake up (e.g. open lid); shutdown -h now => problem! Doing a ps aux | grep systemd, however, does not show any systemd-sleep process that might be hanging. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1441253 Title: hanging suspend job prevents shutdown Status in systemd package in Ubuntu: Won't Fix Bug description: poweroff (systemd poweroff) and reboot no longer work running sudo sytemd poweroff generates this: Failed to start poweroff.target: Transaction is destructive. journal log also shows: Apr 07 18:30:12 alice polkitd(authority=local)[1088]: Registered Authentication Agent for unix-process:32412:2895609 (system bus name :1.194 [/usr/bin/pkttyagent --notify-fd 5 --fallback], object path /org/freedesktop/PolicyKit1/AuthenticationAgent, locale en_US.UTF-8) Apr 07 18:30:12 alice systemd[1]: Requested transaction contradicts existing jobs: Transaction is destructive.
