Upgrade Python to 2.7.x on Debian 6 Squeeze and Install letsencrypt

gistfile1.txt

Hello,

This is a "copy/paste style" How To update Python and then install the LetsEncrypt Client on Debian 6 "Squeeze"

Install some dependencies:

apt-get install build-essential python-pip git libssl-dev libffi-dev python-dev
pip install pythonbrew
pythonbrew_install
source "$HOME/.pythonbrew/etc/bashrc"

Updating Python to version 2.7.10 :

pythonbrew install 2.7.10
pythonbrew switch 2.7.10
pythonbrew use 2.7.10

Installing some Python dependencies:

pip install virtualenv
pip install pyopenssl ndg-httpsclient pyasn1
pip install cryptography

Installing LetsEncrypt Client:

git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt
./letsencrypt-auto

source: https://community.letsencrypt.org/t/how-to-update-python-and-installing-lets-encrypt-client-on-debian-6-squeeze/7118

That no longer works on Debian 6. Can not find python-dev, python-pip and libffi-dev.

it works, thanx.

use debian archives if needed:

DEBIAN ARCHIVE

deb http://archive.debian.org/debian/ squeeze main non-free contrib
deb-src http://archive.debian.org/debian/ squeeze main non-free contrib

I had to do: pip install pythonbrew --index-url=https://pypi.python.org/simple/

How can it work if Debian 6 doesn't have TLS1.2. I get this error:

Downloading/unpacking pythonbrew
