Hello, I have found an interesting bug with guix.

When I try to import ~yasnippet~ from melpa, the command is unable to find the 'refs/remotes/origin/HEAD'.

How to reproduce:

#+begin_src shell :results output :epilogue ":"

guix import elpa -a melpa yasnippet 2>&1

#+end_src

#+RESULTS:

#+begin_example

Backtrace:
