Please teach me how to diagnose why Ubuntu 24.04 randomly restarts on me

My Ubuntu 24.04 machine will randomly restart. Often it hangs while doing so. Sometimes it is successful.

I am looking for an answer that will guide me through the steps I should take to home in on why this is happening. I would like to learn the steps to take to solve this mystery for myself.

I'm running Linux 6.17.0-35-generic on 24.04 with Wayland windowing and Gnome 46 (in case that makes a difference to the steps I should take).

Top Answer/Comment:

Comment: For starters I'd likely start looking in the systemd journal (journalctl) and scan the messages prior to the restart... if you know the date/time of restart it'll be easier; but the messages aren't that difficult to work out (as you mostly want to look for the unusual messages; though if you've not explored the logs before everything will likely look unusual!). You can use normal POSIX style searches there too
