Comment 1 for bug 1868706

At the moment the main suspect is the systemd-tty-ask (which would block with a password prompt), although it might be a long shot. I've just tried with the latest focal desktop image, there were lots of debs to upgrade (including snapd) but I couldn't reproduce it. The postinst is relatively simple, it just starts all mount units of snaps with a systemctl wrapper.

Could you please:
- paste `pstree -u` output for the pid of systemctl process (the one under 2388's tree)
- paste the output of 'ls -l /proc/<systemctl pid>/fd/0'
- attach /var/log/auth.log

Thank you!
