This is the raw process used to install Jellyfin on Ubuntu. Ubuntu supports the latest packages unlike the RHEL Linux flavors. This is unfortunate since the clients used for the Fire TV sticks and the like require the latest version of Jellyfin.

As a bonus, I was able to copy over the metadata and everything seems to be working just fine after a few tweaks.
