I think the root of the problem is that GPG can't find pinentry.

With Guix, it should work automatically if you install GPG and a
pinentry to your user's profile. [0]

When installed via config.scm, you should set "pinentry-program" with
the right path, either on gpg-agent's command line or in
~/.gnupg/gpg-agent.conf.

e5b44b06b3f, which fixed a longstanding UX bug
