Oh fuck off. They only mentioned four package managers, and they misspelled one of them. It’s on dnf, with yum. It’s an RPM. Get it on Snap. It’s an AppImage. Install it from source. It’s an apk. Get it with Homebrew.

Bazzite runs the SteamOS interface. It’s extremely user friendly. It’s designed to look like a console.

For my parents, I got a $150 N100 mini PC (tiny little thing), installed Bazzite, installed Jellyfin, and got the Pepper Jobs W10 Gyro remote. You have to configure Jellyfin to know it’s running on a TV and to accept keyboard input (the remote acts like a keyboard), but then everything works great. It’s a little over your budget, with the added remote.
