please reboot with this kernel boot parameter added:
systemd.log_level=debug
Then let the system boot up, and then perform a shutdown, to reproduce
the problem. Then start the system back up (you can remove the kernel
boot parameter) and capture the previous boot's journal, which should
include the problem reproduction while debug is enabled; you can use the
command:
$ journalctl -k -b -1 > /tmp/lp1905166.log
which will capture the log output from the previous boot.

Title:
systemd-shutdown cannot detach DM
Status in systemd package in Ubuntu:
Incomplete
Bug description:
when powering down the system systemd cannot unmount /
systemd-shutdown[1]: Could not detach DM /dev/dm-0: Device or resource busy
systemd-shutdown[1]: Failed to finalize DM devices, ignoring
reboot: Power down
as a result at each startup the filesystem is checked:
Press Ctrl+C to cancel all filesystem checks in progress
If systemd cannot unmount / that might not be a problem but it should
be less noisy and not result in a filesystem check after each reboot.
