In short: install battle net launcher, the use that to install any blizzard game.
I’ve had luck with Lutris in the past: Install Lutris, search for the battle net installer, once that is installed in it’s own wine prefix you install the games as usually and it will end up in the same prefix.
Last time I was having problems though, so I setup a wine prefix via winetricks instead and installed the same fonts that the Lutris install script adds. Then I got it running.
Well I try to do that, but I keep getting this error:
collapsed inline media
Looks related to a C++ issue. Is Winetricks enabled in the Lutris wine Runner settings?
Winetricks is enabled. I actually managed to get past this issue by selecting another installation folder, now I'm able to technically complete but not complete the installation, as after the login-screen of Battle.net it hangs on this instead

wine-ge-8.26 is quite old now. Get the latest one, 10.something, and see if it solves your issues. Can't remember how you update Wine/Proton in Lutris. Protonup-QT is a great helper to get newer Wine versions for everything.
It's been a while since I have been messing around with Lutris. But the general way of installing WoW or any other thing is basically the same in Lutris, Heroic, Bottles, Steam or Wine without any helper. Though I would advice against using Steam because it creates a new prefix for every new exe you throw at it, unless you tell it otherwise.
Common problems (don't remember if they apply to Battle.net) are that you need to install the Visual C++ Runtime (vcredist), .Net Runtime and some fonts. You can do that with Winetricks or downloading the respective installers from Microsoft. You usually don't have to install all fonts, that'd take a long time. Arial or maybe Helvetica are usually enough.
That is exactly where I had to give up as well. It's the bad file descriptor error.
On my Debian Trixie system, kernel32.dll is in the
libwinepackage:I have no idea what Linux distribution you're using, but if it's Debian-family, maybe:
That'll get both the 32-bit and 64-bit WINE libraries.
It sounds like Battle.net is a 32-bit Windows binary, whereas World of Warcraft itself is a 64-bit binary. I assume that the Battle.net binary might also be a 32-bit binary, and it looks like you're running a 64-bit WINE binary (see the x86_64 thing in the above path that Lutris is running). Maybe you only have the 64-bit WINE libraries installed, and it can't run the 32-bit Battle.net installer? I'm guessing, mind.
I don't use Lutris, so can't provide any advice there.
This is unlikely to work, since kernel32.dll is expected to come from and match the Wine build used to run the game/launcher, and Debian's Wine is pretty much vanilla while Blizzard games often require patched Wine variants.
Debian users will want to enable the i386 architecture alongside the native amd64, then install Debian's wine package to pull in Wine dependencies, and then use a game manager like Lutris or Bottles with a Wine variant like GE-Proton to run the game.
