Hi,
I could solve this problems in two steps, first I installed Debian to
get more information about the error, so this appears at the end...
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
With that information, I could find the solution here:
https://bugzilla.kernel.org/show_bug.cgi?id=206571
Go into the BIOS of the laptop, under Virtualization, and DISABLE the option
"VT for Direct I/O".
Here are the specs of my Thinkpad X! Carbon 4th gen laptop...

I'm going to keep Debian as my primary OS, but I hope this solution
would be also valid for Ubuntu.
P.S. Remember to update your BIOS version to the latest version (1.52 at
the moment).
Have a nice day ;-)
