Site Software - Error: Contact your hosting provider to enable Site Software.

Hello, I am missing cPAddons in my WHM install and I'm unable to find any documentation on enabling site software for Cpanel. When logged in to Cpanel and click the Site software link, I get that error message. All the documentation that I have found says go here click this, but the here and the this are missing from WHM, specifically cPAddons (Image Below). Can someone point me in the direction of enabling Site Software so the links will appear? My ultimate goal is to make WHMCS available for users in site software. Thanks in advance! Andrew UPDATE: As usual, after I posted, I found a note in the documentation that states "This interface does not appear on servers running the Ubuntu" operating system. " So now I know. Does anyone know if there is a workaround for this or should I trash everything and go with CENTOS?
