I assume the messages frfom 10:42 are from the next startup.  Is that correct?

The last message before the logger is shutdown is Stopping Bluetooth
service.  There is no Stopped message but it is possible that is due
to the logger shutting down.  If you can get into the BIOS (and if you
can't you have bigger problems than Ubuntu not shutting down) then try
disabling bluetooth in the BIOS.  Also try disabling USB3 in the BIOS.
I have had some possibly related problems with USB3 and Bluetooth on
my Fujitsu laptop, though mine were problems with suspend/resume.

If that doesn't help then it should be possible to get a systemd
journal.  First make sure that the directory /var/log/journal exists.
If necessary do

sudo mkdir /var/log/journal

and reboot.  Then shutdown and restart again and immediately run

journalctl -b -1 > journal.txt

which should write the journal to that file.  Have a look at the end
of that for possibly some additional information.
