title: Install gitlab-ce on ubuntu server 17.04
body: <p>I'm trying to install the gitlab-ce package on a system running Ubuntu server 17.04. I followed the official installation instructions <a href="https://about.gitlab.com/installation/#ubuntu" rel="noreferrer">here</a>.</p>
  
  <p>First I ran:</p>
  
  <pre><code>sudo apt-get install curl openssh-server ca-certificates postfix
  </code></pre>
  
  <p>I already had all of those installed. Then I ran:</p>
  
  <pre><code>curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash
  </code></pre>
  
  <p>Which also worked fine. But when I try to run</p>
  
  <pre><code>sudo apt-get install gitlab-ce
  </code></pre>
  
  <p>I get the following error message:</p>
  
  <pre><code>Reading package lists... Done
  Building dependency tree       
  Reading state information... Done
  E: Unable to locate package gitlab-ce
  </code></pre>
  
  <p>I know it's possible to install gitlab on Ubuntu server 17.04, since I had already done It on a previous installation. Unfortunately I installed the OS again from scratch and I can't remember how I had installed gitlab.</p>
  
  <p>Thanks for any help in advance!</p>
