If you want to use the above aptitude command output to re-install the
same packages (without having to manipulate the output) you can format
the output with
aptitude search -F "%p" '~i !~M' > installedpackages.txt
(I would not strip out the libraries in this context)

If you are pulling in packages from two or more Ubuntu versions with
apt-pinning, you have to run a search for each version.
