Hi,

as discussed on IRC [1][2] `guix archive --export` is currently broken on
foreign distributions. It fails with the error message:

guix archive: error: corrupt input while restoring archive from #<closed: file 7f27c396e150>

strace reveals `guix authenticate` prints a message to stderr, which the
guix-daemon does not expect:

guile: warning: failed to install locale

Installing the package glibc-locales into root’s user profile (because
guix-daemon.service references that) and restarting the daemon solves the
issue.

Cheers,
Lars

Specifically, the problem occurs after the change in
64cf660f872fb7aaf0d2b463e45b4c756297f743: on the first call to
‘readAuthenticateReply’, the daemon gets a “g” (from the warning above)
instead of a digit as the protocol expects.

Part of the problem is that ‘Agent’ captures stderr in addition to
stdout, which is useful for ‘guix offload’ but a bad idea for ‘guix
authenticate’.

Yup, part of the motivation came from this bug report.

Thanks!
