Hi!
‘guix build /gnu/store/1k8lgjs4al3gp3hri73wrbslbqa16hac-guile-ssh-0.11.3.drv’ (it’s a derivation from
d57660c54907cc6fba8b0adf6295fd2311ada6cf, Oct. 2019) currently enters an
endless substitute query loop (with ci.guix.gnu.org substitutes enabled,
where ci.guix.gnu.org currently lacks this substitute):

The “debug” output substitute is available, but not “out”, and the
daemon keeps asking alternatively for “out” (twice) and “debug” (once)
in a loop.
At that point, ‘guix build’ is stuck waiting for the reply to its
‘build-derivations’ RPC, so the problem appears to be in the daemon.
Running ‘guix build --debug=4 …’ shows this:

Note “there is not substituter that can build it” (for “out”), as well
as the last line.
Nix commit 4ac4f675df3da01b6d814cd328dd3219dd472ac9 (from 2018) touches
code in this area. To be continued…
