just a note on that: ubuntu isn't considered the most private linux distro because it includes closed-source software which might run in the background and track the user. i'm not entirely certain on exact details though, especially not for ubuntu server, so i'm probably wrong lol. also, minecraft, owned by microsoft, is closed-source and the bedrock edition and most recent versions of java edition have telemetry and collect user data. if you want to stick with minecraft, use the 'notelemetry' mod, otherwise i suggest the minetest engine with the mineclone2 game. ok long rant over.
