PPS: Oops, my apologies, the shutdown in a terminal is nonsense :D. You can initiate the shutdown, but not copy and paste from a terminal. I'm running Ubuntu in a systemd-nspawn container, so it works for me.
Just skip that step and post the output of the 'journalctl' command. journalctl -b -1 -n45 or attach the redirected output of journalctl -b -1 -n45 > ~/Desktop/shutdown-log.txt -- ubuntu-studio-users mailing list ubuntu-studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
