Hey! Sorry to hear that. I'm no linux dev and have very little knowledge. That being said, it's questionable whether I can fix the bug. I rely on the MonoKickstart made by other people and of course the framework MonoGame itself.
Have you tried installing the Mono framework (mono-runtime, mono-complete) and run it manually without using the "Kick" file?
Sadly the error doesn't tell me that much, there are a lot of instances in the render function :/
