Does anyone know how I can fix this error that I get when I do a buildout?
sudo -u plone_buildout bin/buildout

This is a legacy behavior which is inconsistent with the new version class introduced in setuptools 8.0. In most cases, conversion to a tuple is unnecessary. For comparison of versions, sort the Version instances directly. If you have another use case requiring the tuple, please file a bug with the setuptools project describing that need.

Answer 1

See here: https://community.plone.org/t/pypi-deprecation-of-support-for-non-sni-clients-breaks-buildout-for-older-plone-versions

Your log shows you have setuptools 30.3.0. That is too old. You need to use a version of setuptools between 36.8.0 and 44.1.1.

1- i install setuptools 44.1.1 and zc.buildout 2.13.1

baobab20@baobab20-VirtualBox:/usr/local/Plone/zeocluster$ pip list

Answer 3

Based on the answer from @webmobile-nailiapps , I was able to have it working (same problem with 4.3.18).

1. I checked (by using the Plone pip) the version of setuptools and zc.buildout were already the suggested ones:

zinstance# ../Python-2.7/bin/pip list

2. I updted buildout.cfg:

 Pillow = 5.1.0

 buildout.sanitycheck = 1.0.2

3. Since there is a chicken and egg problem, I had to manually download setuptools:

zinstance# ../Python-2.7/bin/pip download -d ../buildout-cache/downloads/dist/ setuptools==44.1.1 --no-binary ":all:"

4. Invalidate the existing egg:

zinstance# mv -vi ../buildout-cache/eggs/setuptools-27.3.0-py2.7.egg ../buildout-cache/eggs/setuptools-27.3.0-py2.7.egg.no

At this point it can find the required packages without the SNI/Download error.
