title: Php-gd: PHP Extension gd must be loaded & Unable to locate package
body: <p>Having an issue with php-gd</p>
  
  <p>I inserted this command:</p>
  
  <pre><code>sudo apt-get install php5-curl php5-mcrypt php5-gd php5-common
  </code></pre>
  
  <p>throughout the process to setup Magento but when I went through Validation, this is what I got:</p>
  
  <blockquote>
    <p>"PHP Extension gd must be loaded"</p>
  </blockquote>
  
  <p>When the warning showed up. I tried to install it again using:</p>
  
  <pre><code>sudo apt-get install php5-gd
  </code></pre>
  
  <p>This was the message that I received:</p>
  
  <blockquote>
    <p>"Reading package lists... Done E: Unable to locate package"</p>
  </blockquote>
  
  <p>I Would like some direction on how to fix this Error.</p>
