If you don’t want to spend your time larping sysadmin I’d recommend one of the uBlue images as Kodi, Retroarch and Steam are available from Flathub. If you want to spend your time keeping your media center alive (and possibly learn something about Linux in the process), go ahead with Arch or any of its derivatives. I use Aurora, btw.

Because they’re building a private, not anonymous, instant messenger. They’ve been very open about this.
