Installing Cobbler on Ubuntu 15.10 seems to break apache, how can I fix this?
<p>I am trying to install Cobbler on a brand new Ubuntu 15.10 virtual box but it is not working. When I run the <code>apt-get install cobbler cobbler-web</code> it seems to break apache completely to the point I can't get it working again. </p>

<p>I see this in the apache error log:</p>

<p><code>[wsgi:crit] [pid 8112:tid 140273573488512] mod_wsgi (pid=8112): The mod_python module can not be used on conjunction with mod_wsgi 4.0+. Remove the mod_python module from the Apache configuration.</code></p>

<p>and this in the <code>auth.log</code>:</p>

<p><code>polkitd(authority=local): Unregistered Authentication Agent for unix-process:8081:54865 (system bus name :1.24, object path /org/freedesktop/PolicyKit1/AuthenticationAgent, locale en_US.UTF-8) (disconnected from bus)</code></p>

<p>I have tried removing the <code>mod_python</code> and <code>wsgi</code> modules but apache still doesn't start up. And I think Cobbler uses them anyways, so I kind of need them.</p>

<p>I have also tried disabling polkitd. I don't find any clues when searching for that weird error message.</p>

<p>I was able to install Cobbler on Ubuntu 14.04 pretty easily and apache works fine.</p>

<p>Here is the basic chain of install commands I used:</p>

<pre><code>apt-get update
apt-get install apache2
apt-get install isc-dhcp-server
apt-get install bind9 bind9utils bind9-doc
apt-get install cobbler cobbler-web debmirror mkisofs
</code></pre>
