“Removing a package removes all packaged data, but leaves usually small (modified) user configuration files behind, in case the remove was an accident. Just issuing an installation request for the accidentally removed package will restore its function as before in that case. On the other hand you can get rid of these leftovers by calling purge even on already removed packages. Note that this does not affect any data or configuration stored in your home directory.”
What does purge does that remove don’t?
From apt man page
removes more prob
I think it also removes unused dependencias from whatever you installed but I am not sure.
It removes config files and unused dependencies if I remember correctly
This is correct.
