nix package in edge/testing unusable
I installed the nix packages from edge/testing, and tried to add a channel only to receive the and identical error to #13386. I followed along with what was said in that exchange, but nothing was changed. I'm not sure whether or not this is a bug or just a lack of proper configuration but neither was made clear by #13386. If it is a configuration issue what do I need to do to get nix working?
