I’ve looked around a little, and found some mentions of using Lutris, or running it through Steam (tbh I don’t know how that would work), but I’m not really able to find any guide that explains the process well enough. I’m so used to the game being handled by Blizzard’s Battle.net launcher, so I can’t really wrap my head around how that would work.
I was just trying to get this working yesterday on Fedora 42. I have had it working before, with Lutris. All I did was use the configuration downloaded from the Lutris website. Basically it downloads and installs the Battle.net installer with Wine, so you will be running a custom Wine configuration for Battle.net. From there I was able to install and run World of Warcraft. That was about a year ago.
However, when I last tried it this week, I can install the Battle.net launcher fine, and I can log in, but it will keep giving me errors when I try to actually run it and I can never get to where I can actually install any games. The error is something about it going to sleep, but that’s about as far as I got.
Hopefully someone else can help.
Which Wine runner are you using?
Every so often, a Battle.net update breaks it in Wine, and a workaround must be found. It takes time for these workarounds to make their way into upstream Wine, but game-focused variants like GE-Proton often pick them up early. I suggest trying the latest GE-Proton Wine runner.
