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.
