Did you try pulling with --fallback? I believe if substitute fetching
fails Guix won't build from source unless you add that flag.

Perhaps the error message in Guix pull could be updated to not say

--8<---------------cut here---------------start------------->8---
guix pull: error: You found a bug: the program ...
failed to compute the derivation for Guix ....
Please report the COMPLETE output above by email to <bug-guix@gnu.org>.
--8<---------------cut here---------------end--------------->8---

When the store protocol error is

--8<---------------cut here---------------start------------->8---
ERROR:
  1. &store-protocol-error:
      message: "some substitutes for the outputs of derivation ... failed 
(usually happens due to networking issues); try `--fallback' to build 
derivation from source "
      status: 1
--8<---------------cut here---------------end--------------->8---

and --fallback isn't provided.
