When installing the Guix binary distribution (both the 1.3.0 release and most recent guix-binary on ci.guix.gnu.org) on a new system without enabling substitutes the guix pull or install commands fail when building bash-mesboot0.
  https://guix.gnu.org/manual/en/html_node/Binary-Installation.html

I see the same failure when building bash-mesboot0 on my working Guix installation (with substitutes enabled, but disabled for this build):

--8<---------------cut here---------------start------------->8---
./pre-inst-env guix build --no-substitutes -e '(@@ (gnu packages commencement) bash-mesboot0)'
--8<---------------cut here---------------end--------------->8---

The error from the log:

--8<---------------cut here---------------start------------->8---

The ci builds are marked successful, but the raw log file is either empty or appears to substitute an earlier build.
