I don't want the system to shutdown in the middle of the upgrade, but I've already started the upgrade in the GUI.

Is there a better way, maybe involving the apt lock?

EDIT: Thank you for all the helpful suggestions. Hopefully this helps the next person. My upgrade actually finished on its own while I was posting. 😂

Your GUI tool is probably running apt under the hood. You can find the PID of the apt process and do something like this:

waitpid <pid> && poweroff

If you are afraid it has something to do after the apt process dies, you can add some additional arbitrary delay like this:

waitpid <pid> && sleep <seconds> && poweroff

Alternatively, you can wait until there are no processes matching a regex with pidwait <regex>.
