Awesome!

This issue is resolved in guix master, which as we know is different
than what got installed on your system.

This is because you need to authorize hydra.gnu.org for fetching
substitutes, it is not authorized by default.  You need to run:

  guix archive --authorize < 
/gnu/store/p8wran9sj59ryl2fz2vlrhzy55xh7hny-guix-0.6.20b1d19/share/guix/hydra.gnu.org.pub

I think it would be nice if hydra.gnu.org was authorized by default.

Thanks for trying things out!
