  <p>How does one go about fixing this? I read that I may need to do </p>
  
  <p>sudo apt-get install php-xml</p>
  
  <p>I have done this and everything went ok but still doesn't change it to installed. </p>
  
  <p>FYI: I have only been using this OS for a few days so please go nice on me :) </p>
