Presumably what this means is that the remote machine rejected the store
item we sent it.

To fix it, you need to authorize the signing key of the first machine on
the second machine, using ‘guix archive --authorize’.

You also need to do the reverse and ‘guix offload test’ will also check
that.

Can you make sure the machines are authorized by each other?  (Check
/etc/guix/acl on each.)

HTH,
Ludo’.
