Just in case, using recent guix-daemon as 3f59fd6, I see:

And I do not know which other substitute URLs are since I pass the
option ’--substitute-urls=https://ci.guix.gnu.org’; both to guix-daemon
and to “guix shell”.

Last, I start to see the progress bar, then something happens and I only
see this:

No more progress bars.
