Ouch!  That because Ludo pushed commit [1]
5fb77cce01f21a03b8f5a9c873067691cf09d057 to
https://gitlab.inria.fr/guix-hpc/guix-past but not to
https://codeberg.org/guix-science/guix-past.

In the meantime, you pulled and thus you get this 5fb77cc because it was
still the reference of the old location (inria).  Then you pulled again
but this time using the new location (codeberg).  And bang!

Somehow, that’s a migration typo. :-)  And we cannot do more now it’s
done.

As explained, it is indirectly pulled via guix-gaming-channels [2].

In other words, the scenario reads:

 1. Migration of guix-past from Inria to Codeberg
 2. 5fb77cc pushed to guix-past Inria
 3. guix-gaming-channels had not yet updated their dependency (guix-past)
 4. you pulled, so fetched 5fb77cc from guix-past Inria via the channel
    guix-gaming-channels
 5. guix-gaming-channels updated their dependency reference (guix-past)
 6. you pulled again… Bang!

Well, there is various solutions.  Somehow, you need to clean some cache
to make the authentication passes.  Is it still broken for you?

Cheers,
simon
