Make sure the file /etc/systemd/system/guix-daemon.service includes a
line like this in the Service section:

Environment=GUIX_LOCPATH=/var/guix/profiles/per-user/root/guix-profile/lib/locale

If you make any changes to that file, you need to make them take effect
by running `systemctl daemon-reload && systemctl restart guix-daemon` as
root.

You should also run `env` from the shell where you use Guix and make
sure it includes GUIX_LOCPATH.

For both the systemd service file and your shell, you need to make sure
the value of GUIX_LOCPATH is a directory that contains locales, and that
they are the same version — there will be a directory with a version
number like '2.29' in, for example, '/home/leo/.guix-profile/lib/locale'.

This should all be handled by the installer script so it would be great
to figure out what's wrong.
