title: How to install nginx-full
body: <p>I'm trying to install nginx-full on my 12.04 machine(upgraded from 11.04)
  getting this error with apt-get--</p>
  
  <pre><code>The following packages have unmet dependencies:
  nginx-full : Depends: passenger-common (&gt;= 1:3.0.17) but it is not going to be installed
            Depends: passenger-common (&lt; 1:3.0.18) but it is not going to be installed
  E: Unable to correct problems, you have held broken packages.
  </code></pre>
  
  <p>with aptitude getting this</p>
  
  <pre><code>The following packages have unmet dependencies:
  nginx-light : Conflicts: nginx-full but 1:1.2.3-1~38~natty1 is to be installed.
  nginx-full : Conflicts: nginx-light but 1:1.2.3-1~38~natty1 is installed.
  passenger-common : Depends: libev3 (&gt;= 3.0) which is a virtual package.
    Depends: ruby-rack but it is not going to be installed.
    Depends: passenger-common1.8 (= 1:3.0.17+120~natty1) but it is not going to be installed. or
           passenger-common1.9.1 (= 1:3.0.17+120~natty1) but it is not going to be installed.
  </code></pre>
  
  <p>When I try to install <code>passenger-common</code> it depends on <code>libev3</code> which is not available.
  How can I solve this problem.
  Output of <code>dpkg --get-selections | grep hold</code> this is empty.</p>
