In this chapter, we have taken a whirlwind tour through the intricacies of troubleshooting package management. There is always much more ground to cover, but for the purpose of system administration, you have not only discovered a series of tools that can be used to overcome a wealth of common issues related to Yum, but we have also discussed the ability to extend Yum through a variety of plugins, install third-party repositories, enable Yum to download RPM packages, and restore an RPM database.

So, as you can see, and before we move on to a discussion regarding users, directories, and files, with some lateral thinking and a little practice, you should now be well on your way to being able to troubleshoot an entire host of problems and make almost any package management issue a thing of the past.
