My first suggestion is to follow the advice of the error message:
run "guix pull --fallback" (though it could be that this is not
possible, I remember opening a related bug but I could be wrong).

Correction: I opened the bug for offloading, but not for pull.

[user@abyayala ~]$ guix pull --fallback
guix pull: error: fallback: unrecognized option

This is possibly not the root of your problem, but could you open a bug
about guix pull not supporting fallback?

Thanks!

This should be fixed as you read it (just the time for nginx to expire
the cached 404.)

(For the curious, I fixed it by running:

  wget -O - https://hydra.gnu.org/1drx7dy1zakc0xs60nb0im1jbvxp11dj.narinfo

which told ‘guix publish’ to regenerate the nar corresponding to this
narinfo.  The problem we had here was that the nginx caches had cached
the narinfo but not the nar, and ‘guix publish’ currently only
generate nars when their narinfo is first queried.)

Thanks for your report!

I fixed it yesterday, let me know how that goes.

There seems to be a reservoir of similar bugs. Here is the one I just 
ran into:

hash mismatch in downloaded path

Does hydra have any kind of self-checking mechanism? It would be nice if 
such issues would be resolved automatically.

Looks like it.  :-/  The hope with the new ‘guix publish --cache’ is
that these issues will vanish over time; the 404s that were reported are
for older store items for which we still had old entries in cache.

This hash mismatch is a different story: this package did not build
deterministically, caches have kept the data (the nar) but they have
updated the meta-data (narinfo), which now advertises a different hash.
IOW, the cached data no longer matches the meta-data.

If we were not running nginx caches in front of ‘guix publish --cache’,
we would not have these problems.  However, we need those caches to
distribute the load.

Long-term the best option of course is to have all packages be
bit-reproducible, but until we get there, I’m not sure how to address
it.  Thoughts anyone?

Thanks for your report,
Ludo’.
