`(authorize? #t)` seems working, it does `guix archive --authorize <
local-key` on remote machine before reconfiguring, but after
reconfiguration is finished the value of /etc/guix/acl is reset by
guix-service-type and for some reason the error message you mentioned
appears.  Despite the error message the new generation is created and
new configuration is applied.  It seems something like copying auxiliary
file to remote store happens after reconfiguration is finished.  Will
try to investigate that, when will have some free time.

For now I do the same trick with changing the configuration for
guix-service-type:
