The title says it all: guix download https://fedorahosted.org/releases/x/m/xmlto/xmlto-0.0.25.tar.bz2 results in ERROR: missing interface for module (gnutls) failed to download "guix-file.Oty9Cl" from "https://fedorahosted.org/releases/x/m/xmlto/xmlto-0.0.25.tar.bz2" guix download: error: https://fedorahosted.org/releases/x/m/xmlto/xmlto-0.0.25.tar.bz2: download failed (under guile 2.0.5-deb+1-3). Since guix build -S works on the same file, something needs probably to be ported from guix build to guix download. Andreas
