says that I should loo for substitutes authorization keys in
I'm on a laptop with GuixSD on it and I don't understand: which is my prefix ?
I'm asking this because Efraim invited me to use his substitute server on the irc channel and I don't know how to set it up
I want to use his substitute server because I'd like to build the installation image from the branch with the graphical installer, in order to test it in a visrtual machine
But when I tried to build the installation image I got this (tl;dr linux-libre-4.13.2 missing)
~/projects/graphical-installer_guix [env]$ ./pre-inst-env guix system disk-image gnu/system/install.scm guix system: warning: Your Guix installation is 17 days old. guix system: warning: Consider running 'guix pull' followed by 'guix system reconfigure' to get up-to-date packages and security updates.
