This is because unibilium uses ‘git-fetch’, and currently ‘guix refresh
-u’ only knows how to download tarballs, it doesn’t know how to make Git
checkouts.

Commit 0bd1498fc40820be35125cc0a62482d015b58e9b fixes the issue by at
least reporting a proper error message.

We’ll have to adjust <upstream-source> to support not just tarball URLs,
as is currently the case, but also Git references.

Thanks,
Ludo’.
