I understand that Ubuntu 12.04 will be supported for 5 years. Is this true for all other variations of ubuntu too? For example, will lubuntu 12.04, xubuntu 12.04 and the rest also be supported for 5 years?
And if not, does that mean it's better to install ubuntu 12.04 and then maybe
sudo aptitude install lxde
or
sudo aptitude install xfce
