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. 😂
Why do you need the
while true?Otherwise it’d only check for the lock once. It’d run, go “oops, apt is in use!”, and quit, and never check again.
The loop here is what makes it check again at all.

I suppose it would be useful for flakey internet connection, then your update would restart 5 minutes after losing the connection. It surely has a yucky aftertaste, though.
No, the idea was that
apt updatewould keep failing while the system upgrade was running (and holding the lock):$ apt update E: Could not get lock /var/lib/apt/lists/lock. It is held by process 1704856 (apt) N: Be aware that removing the lock file is not a solution and may break your system. E: Unable to lock directory /var/lib/apt/lists/But there are better ways of waiting for a process to finish, that other people have shared
