Proper way to install pip on Ubuntu : <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>
