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. 😂
From the old world of UNIX: Using UNIX is always a series of small epiphanies. You will keep finding new options, tools, ideas, and shell snippets that will continually expand your skills.
I’ve been using UNIX and then Linux since 1996. I find new little bits any time I go look. It’s a lifetime of curiosity awaiting for you.
