hi all
A) Please add the following flag to your certbot-auto commands
--no-self-upgrade (certbot-auto only) prevent the certbot-auto script
from upgrading itself to newer released versions
It's good to upgrade certbot-auto regulalry however this should be done in a controlled manner (i.e. where you can choose)
B) The root cause was that the certificate served by PyPI was having an issue. As the packages are usually obtained from there the issue and the resolution lie with PyPi fixing their certificate related issues
Well done @fracolo for identifying the root cause
