Hello, I've looked more into this. Upstream does admit that shutdown/reboot commands via systemd may fail. And the recommendation there is to progressively use bigger hammers.
See: https://github.com/systemd/systemd/issues/3282 So i believe you should be trying to: $ systemctl poweroff $ systemctl -f poweroff $ systemctl -ff poweroff (or reboot, or whatever the comamnd you need/want) Specifically, with upgrade from upstart to systemd, and re-exec, we may not shutdown cleanly, and that should be ok. ** Bug watch added: github.com/systemd/systemd/issues #3282 https://github.com/systemd/systemd/issues/3282 ** Changed in: systemd (Ubuntu) Status: Confirmed => Incomplete ** Changed in: systemd (Ubuntu Xenial) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1670291 Title: Landscape: Upgrade 14.04.5 to 16.04.2 fails unable to reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/landscape-client/+bug/1670291/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
