SOLVED! Here is what worked for me:
Original Problem: I am updating FOG 1.1.1 to 1.2.0 and when it got to the part of the installation where the installer
Setting up and Installing Apache Web Server... failedI fixed this by updateing Ubuntu to 12.04 and running:
apt-get install libapache2-mod-php5That got me past the Apache initialization.
The next issue I had was the Database Schema Installer failed and threw HUNDREDS of errors at me. this was fixed by reseting the mySQL password. I found instructions to do so here: http://www.rackspace.com/knowledge_center/article/mysql-resetting-a-lost-mysql-root-password
