In this chapter, you learned how to work with packages in Ubuntu and CentOS, but the skills learned will help you to manage packages in any Linux distribution. You have learned how to work with both
.rpm packages, and also the newer ones such as flatpaks and snaps. You will use those skills in every chapter of the book, as well as in your day job as a systems administrator.
Furthermore, we tackled with the process of building an RPM package by walking you through the process of creating an
rpm file from a simple bash script.
In the next chapter, we will show you how to manage user accounts and permissions, when you will be introduced to general concepts and specific tools.
