Tried Mint, Nobara, CachyOS, Bazzite etc. All result in the same thing. At some point of the installation process, it just hangs on the Wine window that says “The Wine configuration in [home folder] is being updated, please wait…”.
Meanwhile the Lutris window just says:
"Started process blah blah blah…
Start monitoring process.
Monitored process eited.
Initial process has exited (return code: 256)
All processes have quit
Exit with return code 256.
Try installing the gaming-meta package (inspired by cachyOS). With this Meta package Battlenet will install properly (Battlenet requires python-protobuf) but i’m stuck with BLZBNTBNA00000005 Error on the Battlenet Frontpage. I’m still figuering out…
Solution: wine-10.8-staging-tkg-ntsync-x86_64 works without a hassle.
Are you using the same home folder? I move my partition around so thought I would ask. Best bet for getting battlenet to work seems to be one of the 10 or higher versions of proton or GE
Battlenet changed something fairly recently and it seems to be 10 and beyond have changes that allow them to work with battlenet
What wine version have you select in runner settings? Battlenet app doesn’t works properly with vanilla wine by default, you need proton 10 or ge-proton 10 (I use ge-proton 10-10). If it is not installed, you can use protonup to download ge-proton. Next open lutris, go Settings → Runners → Wine → push Settings button and select wine version you want to use. Next you can install Battlenet. I cheched it and it works on Arch with lutris 0.5.20
In the end I gave up. Couldn’t get it working under Lutris. Got it working perfectly fine under Steam with Proton anyways. Lutris doesn’t appear to have any way for the user to load in custom runners so there was never any ability for me to use Steam’s Proton under Lutris.
