Here's a recent excerpt of the console output from guix publish running
Hydra.  Is this expected?

Fixed in ffa5e0a6d2851832b7f0e6f943bc69e69e1bc8b0.

The consequence of this bug is that ‘guix publish --cache’ would always
return 404 for narinfos corresponding to already-compressed files
(files with a name ending in .gz, .xz, etc., such as source tarballs.)

Consequently, clients would download source tarballs from upstream or
from the /file URL rather than as a substitute.  Thus, this should be
almost invisible to users.

So we’ll upgrade ‘guix publish’ on hydra & bayfront, but no need to
rush, I think.

Thanks,
Ludo’.
