I used this repo to install jellyfin app on my Samsung TV https://github.com/Apps2Samsung/Apps2Samsung

Capslock as a layer key to turn hjkl into arrow keys. Easy to setup using Kanata!

What makes you think that? Their website has instructions for installation via a Linux box. https://www.ventoy.net/en/doc_start.html

Adding on to other suggestions, if you’re not aware of Ventoy it’s a very handy tool. Using it you can have a USB drive with several live images on it which you can choose at boot time. Great for quick testing, just drop an ISO in a folder!
