There are two editions: Java and Bedrock. Bedrock is the one that's got Realms, which is the easy way to get servers running.

Have this problem with my brother and nephew, would love to get the lad on Linux, but this is a real obstacle.

Java edition can also use Realms. I'm playing on a realm using Linux Java edition and the official launcher now.

Oh aye? I'll have a look into that, cheers. Totally had it in my head that was a blocker.
