IMHO, this collection raises two questions:

  1. Why does it happen?  To say it explicitly, I am almost sure that
  something is not smoothly working as expected on server side.  For
  instance, I had ‘guix pull’ troubles with a machine and I am doubtful
  that this machine has network issue (this machine is using the fast
  network link of my Univ. employer :-))

  2. What could be done on client side for reducing the annoyance?  I
  agree that substitute failures should be better handled.  For example,
  retry 3 times then display an error message.  Etc.


Cheers,
simon

PS: About #2, please give a look at these annoyances:

  + Issue 1 and 2: Options --fallabck and --no-substitutes
  + Issue 3: Non consistent message for substitutes and/or fallback
