The problem is that Nix caches NAR info in /nix/var/nix/binary-cache-v2.sqlite.
 So if NARs get removed from nixos.org/binary-cache, you may still have a cached
reference to them.  Perhaps Nix should do an automatic fallback in that case...

Workaround is to delete /nix/var/nix/binary-cache-v2.sqlite.
