Maintaining all packages when reinstalling the ubuntu OS?

[Md Ashickur Rahman Noor]

You can use aptoncd to backup all packages that you have downloaded if they
are still in /var/cache/apt/archive directory.

Another way you can use remastersys to make your current Ubuntu a new distro
as an iso file, then install the new distro, you will found all the packages
you have installed in your Ubuntu.
