Sorry, but right now there is no official support for Linux. For what it’s worth, the last time I checked the Windows-version was actually runnable albeit a bit ugly on Linux when compiled using the MonoDevelop etc.
For the future if there’s sufficient interest we may see if it’s possible to port the Mac-version to MonoDevelop and Linux. On of the problems with Linux is the fragmentation of distributions. One doesn’t just support Linux. There’s no such thing. There are a zillion different Linux-distributions. We’d literally have to support perhaps a dozen builds and then test them… Doesn’t seem likely to happen unless someone sponsors the development and maintenance unfortunately.
A third option is that someone from the community pitches in and uses our open source to build a Linux version and the various distribution support required.
