That indicates that it’s failing to offload to one of the ‘localhost’ build machines specified in /etc/guix/machines.scm. Normally there’s an SSH tunnel set up for those, but I guess it broke. Perhaps we can update /etc/guix/machines.scm to refer to armhf-linux machines by their WireGuard IP? Thanks, Ludo’.
