One thing that might help (you may already have done it, but it can’t hurt to ask) is to make the systemd journal persistent.  This way you can examine after the fact the log messages and other journal stuff that occur during a system shutdown/restart.  You do that by doing

    sudo mkdir /var/log/journal	 # make the journal persistent

Then reboot.  After that you can do

    sudo journalctl —list-boots

To see a list of boot numbers (32-digit hex IDs) for which the entire journal is available along with the date/times of start and end.

To examine the journal for a particular boot number, use

    sudo journalctl —boot=<boot number>

This is all covered in the journalctl man page, which you’ve probably read, but you might have missed those details.

Another hint about the systemd Journal (and log files in general): when searching for messages relating to, for example, the ntp daemon, it helps to use the “-i” (Ignore case) option.  Sometimes ntp is spelled NTP in log messages.  Same goes for CUPS.
