Senaite Installation Failure at PYTHONHTTPSVERIFY=0 buildout

I was successfully following the installation instructions until I hit this error at buildout. What could be the problem?

I have installed Plone 4.3.20, Zope 2.13.30 and Python 2.7.18.

(senaite) senaite@knh-micropath-senaite:~/senaitelims$ which buildout
(senaite) senaite@knh-micropath-senaite:~/senaitelims$ PYTHONHTTPSVERIFY=0 buildout

An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:

Hi @ronaldm, please help me get unstuck hereā€¦

HI @wwangwe

Is there a reason you want to stay on the 1.3.x version? Are you planning to run Senaite Health?

I would strongly recommend running the Senaite 2.x version.

If you have reason to run 1.3.x we can then pick it up from there and troubleshoot the error
