CentOS 6.x runs python 2.6.6 but letsencrypt client requires python 2.7 [https://github.com/letsencrypt/letsencrypt/issues/1106](https://github.com/letsencrypt/letsencrypt/issues/1106) for centos 6, you can install python 2.7 besides python 2.6 via IUS Community yum repo [https://ius.io/GettingStarted/](https://ius.io/GettingStarted/) and then install python 2.7 ``` yum -y install python27 python27-devel python27-pip python27-setuptools python27-tools python27-virtualenv --enablerepo=ius ``` then do what i do and replace python2 with python 2.7 in letsencrypt-auto script ``` git clone https://github.com/letsencrypt/letsencrypt cd letsencrypt sed -i "s|--python python2|--python python2.7|" letsencrypt-auto ./letsencrypt-auto --verbose ``` ---

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](https://github.com/letsencrypt/letsencrypt/issues/1046) much thanks ---
