Hello,

The command that ran into this bug was:
`guix shell --manifest=guix-psychopy-manifest.scm`

The contents of `guix-psychopy-manifest.scm` were as follows:
```
(use-modules (guix inferior) (guix channels)
             (srfi srfi-1))

(define channels
  (list (channel
         (name 'guix)
         (url "https://git.savannah.gnu.org/git/guix.git")
         (commit
          ;; Last commit with Python 3.8
          "f1eea19c9ae27e5d275b083bbf280e5b59e5e57a"))))

(define inferior
  (inferior-for-channels channels))

(packages->manifest
 (list (first (lookup-inferior-packages inferior "python"))
       (specification->package "git")))
```

The command fetched/downloaded a lot of packages without issues. Then, the following output happened:

As requested by Guix, I am reporting the bug with this email.

I assume this bug happened upon a temporary loss of the internet connection. Running the command anew continued fetching/downloading just fine.

Kind regards
Lasse Schlör

Seems to be the case, yes.  Closing.
