I just noticed that something like: guix copy --to=REMOTE /gnu/store/….drv
seems to work (it actually sends data) but silently fails if the host’s nar signing key is not authorized on REMOTE (that is, the store items are not added to REMOTE’s store but there’s no error message). Same problem with ‘guix offload’ since both use ‘send-files’ in (guix ssh). This is on v0.12.0-3916-g411ba5118. Ludo’.
