HOW TO SAVE INSTALLED PACKAGES LIST
In Terminal write
sudo dpkg --get-selections > installed-software
It creates the file "installed-software" in your /home/[name]/ directory.
Copy this file onto the system you will install these packages to and go to Synaptic, File->Read Markings, and load the file, then choose Apply to download and install packages.
This works for all enabled repositories, but, for example, packages from ppa repositories will not be retrieved (or will be installed in the Ubuntu Universe version)
