3 Update The System

First we have to make sure that all packages on our new Debian system are up-to-date. To do this, we open a terminal (Applications > Accessories > Terminal):

In the terminal, we run

su

to become root. Afterwards, we run the following two commands:

apt-get update

apt-get upgrade

Afterwards, the system should be up-to-date.
