Thank you for your bug report. Could you attach your journalctl log from that shutdown to the bug?
The log on https://launchpadlibrarian.net/419441276/SystemdFailedUnits.txt also shows that some systemd unit are failing on your system, maybe one of those is creating the issue... (also when it's hanging can you switch into another vt for debugging?) ** Changed in: systemd (Ubuntu) Importance: Undecided => Low ** Changed in: systemd (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1824893 Title: When I type systemctl reboot system reaches Target Reboot but then does not reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1824893/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
