I have a strange error/problem with signing git commits with PGP. Following situation
`git` is installed via system configuration `git:send-email` via `guix install` into the user profile ~/.gitconfig has ``` [commit] gpgsign = true ``` but trying to sign a git commit fails: ``` git commit -m "test" error: gpg failed to sign the data fatal: failed to write commit object ``` `guix remove git:send-email` does not help, still the same. `guix install git` also doesn't help. What is wrong here? P.S: As long as commit signing is not working I cannot become a commiter to the repo. Marius and Ricardo already pledged their support :P
