Broken for the time being
Fusion/Indigo are indeed broken at the moment, and according to those in the know, are currently being worked on, so you should expect to wait a few days before things are back to normal.
Repos Down as well?
The lack of a working config wizard doesn't alarm me, however none of the repos I've tried accessing seem to be pulling anything. So far I've tried to manually install Ex**us and eldorado's repos and I get the same empty repo error.. 😫
Same issue on Fire TV box
Hey there, I'm pretty much having the same problems as OP. When trying to download indigo, when I attempt to open it I get a message saying "slow or no download available: files could not be downloaded at this time: please try again later, attempting to continue"
