My understanding is that the clone is happening through guile-git, which
uses libgit2.  In libgit2's v1.1.0 release notes, I see "[t]he
refs/remotes/origin/HEAD file will be created at clone time to point to
the origin's default branch".  So my current guess is that this clone
was made before guix's libgit2 was 1.1.0.

Does that sound possible (i.e. this clone is from before 2020-12-ish)?
Do you still see the "reference 'refs/remotes/origin/HEAD' not found"
failure if you force a fresh clone?
