title: "make_sock: could not bind to address [::]:443" when restarting apache (installing trac and mod_wsgi)
body: <p>I'm trying to install trac and mod_wsgi over SSL. I tried to manually install it, but that didn't work out so well so I started to follow this: <a href="http://robertbasic.com/blog/trac-on-ubuntu/">trac-on-ubuntu</a></p>
  
  <p>I skipped the svn part because I'd like to use git instead. After the first edit of httpd.conf:</p>
  
  <pre><code>WSGIScriptAlias /trac /var/trac/apache/trac.wsgi
  
  &lt;Directory /var/trac/apache&gt;
      WSGIApplicationGroup %{GLOBAL}
      Order deny,allow
      Allow from all
  &lt;/Directory&gt;
  </code></pre>
  
  <p>I restarted apache only to get this error:</p>
  
  <pre><code>* Restarting web server apache2                                                    
  
  (98)Address already in use: make_sock: could not bind to address [::]:443
  
                                                                       [ OK ]
  </code></pre>
  
  <p>Doing these showed nothing.</p>
  
  <pre><code> netstat -anp | grep 443 
   fuser 443/tcp
  </code></pre>
  
  <p>Doing this didn't yield anything except the grep command that I ran:</p>
  
  <pre><code>ps -aux | grep httpd
  </code></pre>
  
  <p>Why is it saying that something else is using the port when there's nothing showing up?</p>
  
  <p><strong>EDIT:</strong> You guys are going to laugh at this. I had an extra Listen 443 in ports.conf that shouldn't have been there. Removing that solved this.</p>
