Hello, I had problems with that too. It complained about multiple dependencies that it could not download. That was on an old raspbian wheezy image. In the installation guide it specifies raspbian jessie.
Switch to raspbian Jessie or try to build dump1090-fa from GitHub. I tried that but it didn’t work either.
Thanks guys - got it figured out and working fine…and then a new problem:
I went to my profile page and tried to enter my exact location. As I zoomed in to my street on the map, the lat/long stayed the same and indicates Florida (I’m in TX). I was able to accurately enter my elevation as part of the same set-up but now I don’t see the aircraft avatars moving around on the map. I’m still receiving their data (altitude, speed, etc) but no location data and, as I said, no avatars on the map.
Any ideas on how to correctly enter my location - I think that will fix the problem.
