Buildout not working / Couldn't find index page for / Couldn't find a distribution / Disabling non HTTPS access to APIs on PyPI

Well, it seems that all buildouts will fail if you don't already have your eggs downloaded in a cache folder and are using zc.buildout <= 2.9.5. That's why you won't see this error if you already have an environment but it's in CI.

Assuming your python is already a virtualenv, you can run for example:

git clone https://github.com/collective/minimalplone4 && cd minimalplone4 && wget https://bootstrap.pypa.io/bootstrap-buildout.py && python bootstrap-buildout.py && mkdir eggs && bin/buildout buildout:eggs-directory="eggs" buildout:download-cache="eggs" versions:zc.buildout=1.7.1

You will get the error:

Couldn't find index page for 'plone.recipe.zope2instance' (maybe misspelled?)
Getting distribution for 'plone.recipe.zope2instance==4.3'.
Couldn't find index page for 'plone.recipe.zope2instance' (maybe misspelled?)
While:
  Installing.

  Initializing section instance.
  Installing recipe plone.recipe.zope2instance.
  Getting distribution for 'plone.recipe.zope2instance==4.3'.
Error: Couldn't find a distribution for 'plone.recipe.zope2instance==4.3'.

Trying from 1.7.1 to all new buildout versions fail, it works only when we are in 2.9.5. Try for yourself:

git clone https://github.com/collective/minimalplone4 && cd minimalplone4 && wget https://bootstrap.pypa.io/bootstrap-buildout.py && python bootstrap-buildout.py && mkdir eggs && bin/buildout buildout:eggs-directory="eggs" buildout:download-cache="eggs" versions:zc.buildout=2.9.5

The magic is this commit: https://github.com/buildout/buildout/commit/fac9979f516fe1b080258f9b367401a8cc1832e8#diff-db23dcd814354c954091a9b90dbfd92a funny though that if I add index = https://pypi.python.org/simple in my buildout it doesn't work, I need to upgrade zc.buildout to 2.9.5.

FYI @hvelarde and @mauritsvanrees
. I think a change in https://github.com/collective/buildout.plonetest pinning zc.buildout is needed with this justification. More implications in Plone will come, that's why I'm posting it here. Maybe https://github.com/plone/Products.CMFPlone/issues/1502 will need to be revisited.
