title: Frameworks for a Linux auto updater
body: <p>Basically, there is a webapp that runs on the localhost on ubuntu. </p>
  
  <p>I want to be able to implement an update or two from my side, and have the few machines that will be running the webapp also receive the update on their end. (All the machines that run the webapp on their localhost also have internet connectivity)</p>
  
  <p>I thought of 
  1) A SQL server that holds simply the latest version
  2) The webapp connects to the server and checks the latest version and its own version</p>
  
  <p>Beyond this, I'm a bit lost. I was hoping someone could steer me in the right direction for framework or some text that outlines how to implement this sort of thing. </p>
  
  <p>-Apologizing in advance if the question is too vague/non-descriptive</p>
