Roon 1.7 on WINE

I have wasted hours and hours trying to get this to work on Ubuntu 18.04. I’ve used the github RoPiess roon_on_wine script referenced above. I’ve tried multiple versions of dotnet. I’ve used the stable wine release, and used the developer release. I’ve tried installing mono first. Tried installing dotnet first, and also letting the aforemened script install it as Roon installs. All this has been done wiping Wine entirely off my system, before I try another method. Nothing works.

Is there a current, tested, step-by-step method for making this work on Ubuntu 18.04?

Thanks in advance. Short of some great advice from someone, I’ve wasted enough hours trying to get this to work on my own. Frustrating.
