I already have dotnet installed natively (driver, runtime, SDK, and targeting pack). If I could figure out exactly what was calling the error I could have a better sense of what’s going on.
The weird thing is that the game itself is running Mono, which Lutris appears to automatically set up when creating a prefix, and even if the launcher/game isn’t recognizing it, I don’t know why it would be trying to use .NET, let alone installing and accessing prerequisites outside of the prefix.
The game_slug is just an internal ID for Lutris, it would be used for if/when I upload the installation script to the Lutris website.
Installation through Steam was a no-go, I’m not sure Steam and stock Proton have the tools required to get this running, and Heroic likely wouldn’t be much different.
The game itself is an alpha-test under NDA, so I can’t disclose too much, (and why I haven’t been able to find much helpful information searching online). It has a standalone installer and launcher which is what I believe is causing the most issues. I can get in contact with the devs but I’m trying to avoid bugging them since there is not currently planned support for Linux.
