How can I upgrade Python to 2.7.9 on Ubuntu 14.4?
Solution 1:
ppa:fkrull/deadsnakes is the latest version of python2.7
sudo add-apt-repository ppa:fkrull/deadsnakes
sudo apt-get update
sudo apt-get upgrade
It will upgrade python to 2.7.10
Solution 2:
You can use pyenv:
git clone https://github.com/pyenv/pyenv.git ~/.pyenv
git clone https://github.com/pyenv/pyenv-virtualenv.git ~/.pyenv/plugins/pyenv-virtualenv
Then add
# for PyEnv
export PYENV_ROOT="$HOME/.pyenv"
export PATH="$HOME/.pyenv/bin:$PATH"
export PATH="$HOME/.pyenv/shims:$PATH"
eval "$(pyenv init -)"
to .bash_profile then you can see the python version you want to install or update:
pyenv install --list
want python 2.7.10? you can try:
pyenv virtualenv 2.7.10
Hope it can help you.

I'm not a fan of previous answers suggesting installing from various PPAs. No disrespect intended, but I don't know the people who built them and I have no idea what might be in there. In any environment where someone has to answer to a security professional that practice would be frowned upon.
I just found that downloading 2.7.9 from source and installing it side-by-side was a good start. This awesome blog post covered the steps. (recreated here to conform to stack overflow guidelines)
wget https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tgz
tar xfz Python-2.7.9.tgz
cd Python-2.7.9/
./configure --prefix /usr/local/lib/python2.7.9
make
make install
Test if the version works
/usr/local/lib/python2.7.9/bin/python -V
Python 2.7.9
Now that I have 2.7.9 installed I can call it directly or symlink to it from wherever I want. (or copy it into a virtualenv etc.)
And note that I got here from a situation where I was getting insecure platform warnings, and SNI Missing warnings. Which led me here. I imagine many people are finding this question through the same path. And if that's why you're here this snippet may be of use to you too
pip install urllib3[secure]

Here is new upgraded third party repository:
sudo add-apt-repository ppa:jonathonf/python-2.7
sudo apt-get update
sudo apt-get install python2.7
python --version
Solution 5:
You can go to the python.org and download the .tar.gz file compile and install it. You will need the basic tools in order to compile the source code. I don't remember if the "build-essential" package will suffice but give it a try.
