Hello,
I tried out the installation via ./letsencrypt-auto, with the intention of only using the client to
acquire a cert, then using Plesk to install the cert. CentOS 6.6, Plesk 11.5.30.
I am having the same problem w/ python version.
Python 2.6 is on the way of being supported again
I am monitoring the issue for updates. letsencrypt-auto doesn't work with Python 2.6 · Issue #1046 · certbot/certbot · GitHub
much thanks
