CIS305 Advance Linux Networking – Package Management

Working with Systemd & Dnf Package Management in Linux

Upon completion of this lab the student will be able to:

1. Describe how to update the operating system packages2. Demonstrate the process of how to install a specific package3. Describe how to show all install packages

Background:

In this lab the student will work with the most commonly used Linux command concepts. You will often find yourself having to know how to modify the initial operating system packages that where installed with the operating system with newer packages as they become available. Package managers download and install software and their updates as needed. This can be accomplished from the command line as well as from the GUI. Linux uses a new system of downloads and updates called systemd.
