If I remove any application with
sudo apt-get remove <applicationName>, the application is removed and then I can remove the repository later on.
I have noticed that certain cached and config files remain in the system. Some take up a large amount of space, e.g. GOOGLE-CHROME. It is hard to find and delete the remaining manually, as I am often not certain whether to delete them or not.
Is there any way to delete an application including the config and cache files along with the application?
