Hi ! I'm still discovering / experimenting with guix thanks to the videos of David Wilson. Sorry if it's not the appropriate place to discuss this. I'm trying to add pam-gnupg without having a graphical login manager. I figured out it should really be as simple as the few lines I added in the attached patch, since the feature has already been implemented for a few graphical login managers. It has been done here : https://issues.guix.gnu.org/47364 So I'm trying to test the patch, have downloaded guix source code, added it in a new branch, updated my channels, used guix shell for setting the environment, but now I get the following error when I try to pull to test my version : guix pull: erreur : Erreur Git : cannot locate remote-tracking branch 'origin/keyring' The patch is straightforward, might not need much testing, but if needed, I would be glad to received some smart advice :) Thanks in advance, thanks for the outstanding work on Guix !
