As seen in <http://hydra.gnu.org/build/54212>, ‘guix authenticate’ could
fail when running in the C locale (as is the case on hydra.gnu.org):

The problem was that it could in some cases produce a signature sexp
with an invalid hash value. For example:
guix archive --export
/gnu/store/hyr8lvpbl2lbbkvr5v1qa25895bpcxls-gmp-6.0.0a-guile-builder
would produce an archive with a signature sexp like this (literally):
(signature
(data
(flags pkcs1)
(hash sha256 "^?\vU????{N4?`??eL??x???|1y????{L")
)
[...]
The problem is that the hash value shown here is the result of
substituting non-ASCII characters with question marks and other things.
Obviously signature verification on such a thing would fail, leading to
errors like the one above.
This could happen in some cases, when libgcrypt would choose to use a
byte string representation instead of a hexadecimal string, and is due
to the fact that ‘string->canonical-sexp’ would convert strings passed
to ‘gcry_sexp_new’ to locale encoding.
This is fixed with commit 6030d84 (see that commit for a concrete
example.)

A related issue is the choice of the stdout encoding used by ‘guix
authenticate’, fixed in 6f69588.
This appears to solve this bug.
