The problem is that the (gnutls) module is not in the search path of
‘guix substitute’.

Usually the solution is to start the daemon using something like:

  sudo -E ./pre-inst-env guix-daemon …

so that ‘guix-daemon’ inherits the correct values for ‘GUILE_LOAD_PATH’,
etc.

Does that work for you?

We used to have this suggestion in the doc, but it was reverted in
commit 73a203450d21241eca50375aeb26fb418b287414.  Leo, do you think we
can reinstate it?  I’m not sure why it was reverted in the first place.

Thanks,
Ludo’.
