You can try changing the python-gpg package's version to the last
available upstream version. On PyPi, that's 1.8.0.

Then, try rebuilding the packages that depend on python-gpg (`guix
refresh -l python-gpg python2-gpg`).

Hopefully it all works. Then, you can send a patch with your fix :)

Let us know if you need help!
