After a recent guix pull, I'm getting tracebacks when attempting to run
guix challenge.

I tried switching subsititues to a local caching proxy, not sure if that
could possibly break anything. But after switching back to using the
substitutes directly, the problem still persists.

$ guix --version
guix (GNU guix) 1fa37d1b55b1d25a9d20c7b50a531b763e7a1398

$ guix challenge --substitute-urls="https://berlin.guixsd.org https://mirror.hydra.gnu.org" linux-libre
