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:
[…]

failed to compute the derivation for Guix (version:

Please report it by email to <bug-guix@gnu.org>.
```
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
