Hi!
How do you configure gpg agent? I use home-gpg-agent-service-type (from the module (gnu home services gnupg)) [1], where I use a configuration like this (I use pinentry-qt): (service home-gpg-agent-service-type (home-gpg-agent-configuration (pinentry-program (file-append pinentry-qt "/bin/pinentry-qt")))) [1] - https://guix.gnu.org/manual/devel/en/guix.html#GNU-Privacy-Guard
