Debian uses .deb binary packages and you manually install and uninstall them using dpkg tool.

dpkg has lots of options but maybe the most important or used ones are:

-i

Installs and configures a package

-r

Removes the package but keeps the configuration files on your systems, thus you may reinstall it later and does not need to configure it again

-p

Purges a package, meaning it will remove the package and also all configuration files

How to use it

- To install a .deb package

sudo dpkg -i package.deb

- To uninstall a .deb package

sudo dpkg -r package

- To purge a .deb package

sudo dpkg -p package
