Many php applications have compatibility issues with php 5.3.1. Unfortunately in that is the only version currently available in the aptitude repositories for the latest version of Ubuntu.

Once you have either freshly installed Ubuntu and php, or after you update just your distro and do an apt-get update, you will be on 5.3. There are lots of people with this problem. Many of them have solutions. Most involve running lots of terse commands. Then I ran across this shell script that once you have everything installed for php 5.3 will downgrade your stack to 5.2.10 for you. Since I’ve had trouble finding the original source after a few days, here’s the source in case you need it.

#! /bin/sh
php_packages=dpkg -l | grep php | awk '{print $2}'


sudo apt-get remove $php_packages

sed s/lucid/karmic/g /etc/apt/sources.list | sudo tee /etc/apt/sources.list.d/karmic.list

sudo mkdir -p /etc/apt/preferences.d/

for package in $php_packages;
do echo "Package: $package
Pin: release a=karmic
Pin-Priority: 991
" | sudo tee -a /etc/apt/preferences.d/php
done

sudo apt-get update

sudo apt-get install $php_packages
