title: Proper way to install pip on Ubuntu
body: <p>I'm trying to install the latest version of pip (currently 8.1.2) on the official ubuntu/trusty64 Vagrant box. The box comes with Python 2.7.6 and 3.4.3 pre-installed with apt-get.</p>
  
  <p>I read the <a href="https://pip.pypa.io/en/stable/installing/" rel="noreferrer">pip installation doc</a> and it contains the following warning:</p>
  
  <blockquote>
    <p>Be cautious if you're using a Python install that's managed by your
    operating system or another package manager. get-pip.py does not
    coordinate with those tools, and may leave your system in an
    inconsistent state.</p>
  </blockquote>
  
  <p>Does that mean I cannot install pip using get-pip.py and I am limited to install an older version of it from apt-get?</p>
  
  <p>If there is a better way of installing it, what would it be?</p>
  
  <p>Thanks</p>
