I'm not sure if you meant ‘that fact on its own is useless’ or ‘I 
know how to fix that, but it didn't help’.  If it was the former:

If ‘grep 7D602902D3A2DBB83F8 /etc/guix/acl’ shows output, it is 
authorised.

If it is not authorised, you can download [0] and run
‘sudo guix archive --authorize < bordeaux.guix.gnu.org.pub’.

Kind regards,
