title: How to install older version of Jenkins?
body: <p>I'm installing Jenkins 1.532-1.1 on Ubuntu 12.04, and I need to install it using <code>apt-get</code> repo. I ran following three commands which installs latest Jenkins just fine:</p>
  
  <ul>
  <li><code>wget  -q -O - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | apt-key add -</code></li>
  <li><code>echo "deb http://pkg.jenkins-ci.org/debian binary/" &gt;&gt; /etc/apt/sources.list</code></li>
  <li><code>apt-get update</code></li>
  </ul>
  
  <p>But I need to install this specific version 1.532-1.1 (for a reason that is beyond my control). I tried <code>apt-get install jenkins=1.532-1.1</code>, this gives version not found error. </p>
  
  <p>I've had a look at this link <a href="http://pkg.jenkins-ci.org/debian/">http://pkg.jenkins-ci.org/debian/</a> but installing *.deb is not option for me.</p>
  
  <p>Any idea how I can install jenkins 1.532-1.1 using apt-get?</p>
