This doesn't seem right, I use runelite on linux fine without any extra lutris or wine stuff. As far as I know you don't need the official launcher.

Edit: oh, I understand, I have an old account without the jagex launcher stuff. New accouts apparently need it. Well that sucks for you, I'm sorry.

Have you migrated to a Jagex Account yet? You probably haven't done that which is why you can still play without the official launcher.

You're correct, see my edit above.
