title: Why do I get old versions of nodejs and npm when installing with apt-get?
body: <p>I have executed the following command in Ubuntu 14.04 64-bit. </p>
  
  <pre><code>sudo apt-get update
  sudo apt-get install nodejs modejs-legacy npm
  </code></pre>
  
  <p>I have the versions</p>
  
  <pre><code>npm -v
  1.3.10
  
  nodejs -v
  v0.10.25
  </code></pre>
  
  <p>These are older than the recommended versions for AngularJS 2.</p>
  
  <p>Why does apt-get download old version?
  How do I update to newer versions?</p>
