First, please check that you have substitutes enabled and you are in
fact fetching binaries from ci.guix.info and/or mirror.hydra.gnu.org.
(In recent versions of Guix these are enabled by default.)

Guix is trying to fetch source code from ftp.gnu.org, which is likely
not what you want when using substitutes.  It should fetch sources from
our build farm cache, or even better fetch the built binaries.

It’s failing to fetch the sources, because it cannot verify the TLS
certificate.  You may need to set up environment variables to specify
the location of the certificate bundle.

The manual includes a section on X.509 certificates.

Hope this helps!
