OSX Subversion not working / Poor error message

I don’t know if this still works, but I’m willing to try anything at this point… anyone know the location of this in Linux? In the .config folder for Unreal Engine there’s just something called UnrealBuildTool with a single .ini and in the Epic/UnrealEngine (btw why are there TWO in Linux???) there’s a bunch of folders but find -name “SourceControlSettings.ini” turns up nothing.

Unreal in Windows has no issue using my SVN server, but the Linux version gets the errors mentioned in this thread (and yeah, they’re really poor error messages still after all these years).
