I found this post Amazon Linux -> ImportError: No module named cryptography.hazmat.bindings.openssl.binding - #4 by xinxilas
that gave the following solution
/opt/eff.org/certbot/venv/local/bin/pip install cryptography interface
In my case I had to use sudo with it.
After this, when I issued certbot-auto --help I got
$ certbot-auto --help
Requesting to rerun /usr/local/bin/certbot-auto with root privileges...

ImportError: No module named proxy
I know very little about python so should I just do the same for the proxy module?
ie
sudo /opt/eff.org/certbot/venv/local/bin/pip install proxy
