I did the physical media & Jellyfin install earlier this year. It was not that hard. From the moment I searched “create bootable Linux usb drive” to streaming my first movie on the flat screen TV from a Jellyfin server running on an Ubuntu box took a whole 90 minutes.

The hardest part was figuring out the folder where to save the media on the Ubuntu and give Jeyyfin read permissions on that folder via some Linux commands. It was not that hard because Jellyfin tips and tricks are all over the internet (Reddit for example.)
