Downgrade php 5.3 to 5.2 Ubuntu 12.04 - Dependencies error

[pcrio2]

Hello, im trying to downgrade php to 5.2 following a tutorial:

put the attached karmic.list in /etc/apt/sources.list.d and the attached "php" into /etc/apt/preferences.d.

sudo apt-get update
sudo apt-get remove php5 libapache2-mod-php5 php5-xsl php5-gd php-pear php5-mysql php5-curl php5-memcache
sudo apt-get install php5 libapache2-mod-php5 php5-xsl php5-gd php-pear  php5-mysql php5-curl php5-memcache

When i run the command to install php 5.2 this error appears (Sorry, its in portuguese, i will try to translate it) :

Os pacotes a seguir têm dependências desencontradas:
 libapache2-mod-php5 : Depende: php5-common (= 5.3.10-1ubuntu3) mas 5.2.10.dfsg.1-2ubuntu6 está para ser instalado
E: Impossível corrigir problemas, você manteve (hold) pacotes quebrados.

English

The following packages have dependencies found: 
 libapache2-mod-php5 : Depends: php5-common (= 5.3.10-1ubuntu3) but 5.2.10.dfsg.1-2ubuntu6 is going to be installed
E:  Its impossible to fix this problem, you kept (hold) broken packages.

How do i fix this?

Try to fix the broken packages. Open Synaptic Package Manager and look for messages at the bottom that point to any broken packages or type the following at a terminal window:

sudo apt-get install -f

Look for that required dependencies packages from ubuntu packages and install them:

sudo dpkg -i name.deb
