Summary
In this chapter, we have taken a crash course in the world of package management. As you can see, Ubuntu Server offers an amazing number of software packages and various tools that we can use to manage them. We began the chapter with a discussion of how package management with Ubuntu works, then we worked through installing packages, searching for packages, and managing repositories. We have also discussed best practices for keeping our server up to date, as well as the commands available for us to install the latest updates. Snap packages were also covered, which is an exciting up-and-coming technology that will greatly enhance software distribution on Ubuntu.
In Chapter 4, Navigating and Essential Commands, we'll take a look at foundational commands for navigating the Linux Shell, understanding the filesystem layout, and more.
