Hi Victor.
Simple way.
You can do it manually.
First generate a list of what you have installed on your system. You can do
this by typing the following in the terminal.
sudo dpkg --get-selections | grep '[[:space:]]install$' | \awk '{print
$1}' > package_list
copy your /home and /etc folder to a backup media.
Re install ubuntu 12.04. Restore your backup (remember to set the correct
premissions). Then run the following to reinstall all the program you had
before.
cat package_list | xargs sudo apt-get install
Note that you might have to do some cleaning of the /etc and /home folder
for incompatible settings.
