In the live session, calling `systemctl reboot` (or /sbin/reboot) as root produces the following error:
# systemctl reboot Operation inhibited by "ubuntu" (PID 2297 "gnome-session-b", user ubuntu, reason is "user session inhibited". User ubuntu is logged in on tty2. Please retry operation after closing inhibitors and logging out other users. 'systemd-inhibit' can be used to list active inhibitors. Alternatively, ignore inhibitors and users with `systemctl reboot -i' I was confused why the error was different from what I saw in the Subiquity logs. But curiously: # systemctl reboot > /dev/null Call to Reboot failed: Access denied -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2092438 Title: System fails to restart after install To manage notifications about this bug go to: https://bugs.launchpad.net/subiquity/+bug/2092438/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
