Apologies for this.  The problem was due to the combination of two
issues: a change in how we publish substitutes (see
<https://debbugs.gnu.org/cgi/bugreport.cgi?bug=26201#96>), and a
misconfiguration of nginx at mirror.hydra.gnu.org, which led it to cache
meta-data (“narinfos”) for too long, in turn leading to the above
discrepancy (the mirror thinks it has aspell-dict-en when in fact all it
has is its meta-data).

I believe the latter is addressed by
<https://git.savannah.gnu.org/cgit/guix/maintenance.git/commit/?id=422a350d6b3e3b5b9f73a417aecf7be41510842c>,
though it could take a few days to “refresh” the cache.

At any rate, please let us know if you still experience 404s like this.
The workaround in the meantime is --fallback.

Thanks,
Ludo’.
