bug#69058: Failure when fallback to Disarchive+SWH

[Simon Tournier <zimon.toutoune@gmail.com>]

Hi,

Another example using Git.  It is from v1.1.0.

--8<---------------cut here---------------start------------->8---
$ guix time-machine -q --commit=v1.1.0 -- build -S redkite
guile: warning: failed to install locale

From its definition the package reads:

--8<---------------cut here---------------start------------->8---
(define-public redkite
[...]
       (sha256
        (base32
         "1747w1kg8y9jbl11xi018d85dm38xk7843pz26sh0k5fdv87a10q"))))
--8<---------------cut here---------------end--------------->8---

Then if I manually download it:

--8<---------------cut here---------------start------------->8---
$ wget -O /tmp/content https://archive.softwareheritage.org/api/1/vault/flat/swh:1:dir:d14c0eb6801bca920d1e1baac7a4b9e2a0589728/raw

[...]
/tmp/content        100%[===================>] 129,38K   555KB/s    in 0,2s    
2024-02-11 19:00:33 (555 KB/s) - ‘/tmp/content’ saved [132488/132488]

$ tar xf content
--8<---------------cut here---------------end--------------->8---

And we get the expected value:

--8<---------------cut here---------------start------------->8---
$ guix hash -rx swh:1:dir:d14c0eb6801bca920d1e1baac7a4b9e2a0589728
