In this post, we will see how can install our own Plex server instance on our Ubuntu (or any Debian based) system. Plex allows us to have our own media library (movies, tv shows, music, images, videos) that we can access from any device in our local network or the outside world if we enable it. The only thing that we will need, except for a linux server, is a free Plex account that we will see where you can create, later in the process.
