There are many different flavors of Linux on campus, the majority of which are Debian-based (Ubuntu / Raspbian / Kali). The command line instructions below are suited to these distributions. It is very important to keep Linux powered devices such as the Raspberry Pi up to date as they represent a regular target for attackers. The commands below assume the user is NOT logged in as root, which is another practice that should be followed to reduce risks, along with changing the root password.

First, navigate to the command line, and update your system’s package list by entering the following command:

sudo apt-get update

Next, upgrade all your installed packages to their latest versions with the command:

sudo apt-get dist-upgrade

Performing this task regularly will help protect your device.
