title: Can't install node.js on Linux server
body: <p>I followed some instructions to install node.js on a Linux server and ran in to the following blocks. I started out by doing <code>sudo apt-get install python-software-properties</code> and that worked fine. Then, I did <code>sudo add-apt-repository ppa:chris-lea/node.js</code>. But, wait - there is no command <code>add-apt-repository</code>. OK, so I looked it up and it told me to do  <code>apt-get install software-properties-common</code> and that would have been fine, except it gave me this error: </p>
  
  <pre><code>Reading package lists... Done
  Building dependency tree
  Reading state information... Done
  E: Unable to locate package software-properties-common
  </code></pre>
  
  <p>Well, what can I do to get node.js on my server? Obviously, none of this works and it's Debian, in case you were wondering. I really need help on this. Basically, how can I install <code>software-properties-common</code> if it does not exist? It just won't show up.</p>
