In http://popcon.debian.org/all-popcon-results.gz there is this line:
Package: linux 0 1 0 5
It looks like some people have an actual "linux" binary package installed, which is confusing our scripts - we query python3-popcon with source package names, but that module expects binary package names.

Whoops, yes I missed that previously. Yes, this should be a good approximation for the set-union metric in "most" cases, and I can adjust our scripts to read this instead. It would be best to have the proper metric in place though, for more accuracy.

Understood, I'll work on that when I get some time. Thanks for the pointer!
