Ugh — figured it out — this was dumb on my part. I was running “$ sudo guix archive --authorize < signing-key.pub”, which obviously doesn't extend to input redirection — so nothing was authorized. 

Now I truly ran “# guix archive --authorize < signing-key.pub”, it authorized the key. 

Then I was able to import libreoffice to the store — the directory is there.

However, it's not installed in my profile — “guix package -I” doesn't list it. Running “guix package -i libreoffice” again wants to rebuild it. How do I install the one that's been imported to the store?
