Hi Luther,

In addition to what Leo said, I believe you also need to add this option ...

--substitute-urls=https://berlin.guixsd.org

... to each guix command -or- add it to GUIX_BUILD_OPTIONS -or- add
something like this to your system config ...

(define %my-services
  (modify-services %base-services
    (guix-service-type config =>
		       (guix-configuration
			(inherit config)
			(substitute-urls (list "https://mirror.hydra.gnu.org"
					       "https://hydra.gnu.org"
					       "https://berlin.guixsd.org"
					       ))))))
...
  (services (cons*
             ...
	     %my-services))

HTH - George
