Installing Locally

Some linux distributions (like ubuntu) are debian based, thus they install software through files with a .deb extension.

The program that is responsible for installing .deb files is dpkg.

If you have a .deb file locally, you can install it using dpkg like so:

sudo dpkg -i <path_to_file.deb>

Installing From Repo

There are repos (on the internet, or maybe locally on your computer) that host debian packages. To install from a repo, you use apt or apt-get. apt-get is the lower level command that apt uses. It claims to present a “nicer” interface. Most online code examples use apt-get though.

To install a package using apt-get:

sudo apt-get install <package_name>

Uninstalling

To uninstall a package installed via apt-get cleanly:

sudo apt-get purge --auto-remove packagename

• purge (instead of remove) removes configuration files as well (system wide config files)
• --auto-remove will remove any dependencies of the package that aren’t used by any other installed packages
