Hi Pierre ! That was it, thanks a lot ! Sorry I should have read the docs more carefully.
The command to run on the first machine was ssh root@SECONDMACHINE guix archive --authorize < /etc/guix/signing-key.pub It now says "downloading from http://localhost:8081/nar/gzip/yyrr1zj2ax53pylzp0mq92sgpldk2603-gerbil-0.16"; Cheers, Edouard.
