Importer 'FbxImporter' had unexpected failure!

I hope that someone fixes this soon. I’ve followed A LOT of instructions and nothing has worked. Probably doesn’t help that I’m using Linux, as a few work-around-hacks were Windows/Mac only (like the Autodesk fbx converter solution… can’t download that on Linux). Anyway, I really really hope someone fixes this. I can’t believe it worked just fine so many years ago and now it’s broke?!
