I am wondering if there is a way that I could make a back up of programs or the packages used for installation.
I usually have a handful of programs installed and sometimes I end up having to reinstall my programs whenever I mess something up with the Ubuntu install. These are either by 'apt-get' or by the GNOME store. So I cannot install by a '.deb' package for all programs I have.
So I am wondering if there is a way to excract a program or the packages so that if I need to reinstall them, I can easily do so.
