I really like understanding how stuff work, even when there is no problem. So can the experts explain these observations?
I can run this commend:
sudo apt-get update && sudo apt-get upgrade -y
twice in a day, and the number of headers can be completely different. It can go from 9 to 25, even if nothing has happened between.
I can run Ubuntu Software Updater, then immediately after run that same CLI. The Updater will say I am up to date, while the CLI downloads stuff, sometimes a lot. Aren’t they doing the same thing?
Is it wise or unnecessary to run autoclean and/or autoremove after an update or upgrade? It seems that most of the time, I am removing headers and a few lib files, no more.
