The reason for GNU Guix not showing up in GNOME Boxes appears to be that the ISO9660 download URL is commented: https://gitlab.com/libosinfo/osinfo-db/-/blob/master/data/os/guix.gnu.org/guix-1.1.xml.in#L15 I sent a new MR to add Guix 1.3.0 as well as Guix latest support here: https://gitlab.com/libosinfo/osinfo-db/-/merge_requests/360/diffs?commit_id=e7c8f037e6967edce4076fcf85b1a5bc0a9e2247 Let's see what happens!
