For the simplest example, if I want to remove two package, a and b. I do this:
sudo apt purge --autoremove package-a package-b
If ubuntu doesn't found package-a , it will stop and complain. How to let it automatically skip the package it can't find and just remove the ones it finds?
Suppose I have a lot of package to remove but I don't know which of them are actually in system, therefore I found skipping the "unfound" is very useful.
