Package management with apt and yum

Motivation

Once you have your own Linux system you will want to install additional packages. This is really easy in Linux as Linux distributions come with a packet management system (kind of like the App-Store on your phone), where you only need to search for packets you want and then install them.

Most Linux distributions are either based on debian (E.g. debian, ubuntu, mint, ...) or on redhat (fedora, redhat, centOS, suse, ... ).

The redhat based distributions use yum as their package manager and the debian based use apt-get. Here are the most important commands for package management.

apt-get update    # reload the list of avialable packages (does no update any packages yet)
