You can get it to work on Ubu but you need to troubleshoot it, and it is due to libudev.so.0 no longer being supported for recent Linuxes, its changed to libudev.so.1!
But you cannot ask your users to run through that hurdle so officially, Linux exporter is for commercial purposes, broken.
NodeWebkit needs to update to fix it. :/
No, as of testing a week ago, it's still not fixed.
