apt remove vs purge – Key Differences Explained

aptpackage-managementpurge

I see sudo apt remove package_name and sudo apt purge package_name,
but what is the difference? is one safer than the other or does one remove packages installed by that package?

Best Answer

You can read the manual of apt with

man apt

On line 35 you will find the following

       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.

So in short: remove leaves some config files behind where purge does not. And you can even use purge if later you want to delete those config files.
