Fixed in commit de9d8f0e295928d92e0e5ea43a4e594fa78c76fb.  Now we get:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix copy --to=localhost sed
sending 1 store item to 'localhost'...
guix copy: error: build failed: program `guix-authenticate' failed with exit 
code 1
--8<---------------cut here---------------end--------------->8---
