Hi Lisi, lets start troubleshooting. First without taking a look at log files.
Open a terminal. I suspect Ubuntu Studio Bionic by default provides xfce4-terminal. In the terminal run shutdown -h now to poweroff ("shutdown") or shutdown -r now to reboot ("restart"). It doesn't matter if you use '-h' or '-r' the shutdown processes are the same. Then copy from the terminal and paste to your reply the last around 45 lines or all lines, if there should be less lines, after the shutdown "hangs". Scroll up and take a look at all other lines, perhaps some lines contain 'fails' or similar, or repeated some 'job' appears, if so copy and paste such lines, too. To copy from xfce4-terminal either use the right mouse-click menu, the menu bar's "Edit" menu or when using a shortcut care about using Shit+Ctrl+C (Strg+Alt+C) _not_ Ctrl+C (Strg+C). Btw. usually HTML isn't wanted at mailing lists. Plain text is preferred over HTML, resp. multipart. To paste output from the terminal stay with HTML (if you shouldn't know how to switch between auto-wrapping and unwrapped lines for plain text mails edited with your mailer), since it's better if terminal output gets copied unwrapped. Second with taking a look at a log file. In a terminal run journalctl -b -1 -n45 and copy and paste. An idea strikes me! Usually mailing lists allow to attach small text output to an email. So you could run journalctl -b -1 -n45 > ~/Desktop/shutdown-log.txt and attach the log file from your desktop to an email, instead of copying and pasting it. shutdown -h now > ~/Desktop/shutdown-log.txt 2>&1 won't work. Regards, Ralf PS: This is a more or less dead mailing list. Consider to ask audio related questions at https://lists.linuxaudio.org/listinfo/linux-audio-user . There's much more traffic on this list, you could at least reach one active Ubuntu Studio team member there. Regarding general Ubuntu flavour related request, such as this one, consider to join https://lists.ubuntu.com/mailman/listinfo/ubuntu-users . If I were you, I would resend this request to the Ubuntu users mailing list. -- 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
