Hey there,

Could you specify your issue a bit? If it’s the one with Lunacy crashing at the launch – we’re working on fixing it at the moment. We’re thinking that it’s probably connected with fonts.

System.InvalidOperationException: Default font family name can't be null or empty

Version: 0.10-preview2 I upgraded project IPOCS.JMRI.CONTROL, located at http…s://github.com/GMJS/ipocs.jmri, to preview2 (not committed and pushed yet) and made a build for `linux-arm` using `dotnet publish IPOCS.JMRI.CONTROL -c Release -r linux-arm`. Upon trying to run this on a raspberry pi I'm getting the exception: ``` Unhandled exception.

I have the same problem in Chinese locale.
I install package ttf-mscorefonts-installer and run commands below
fc-cache --force
Finally I add a environment var LC_ALL=C and then it works.
but it is so complex for user.
