How to list all installed packages?
I am on a "grown" system. My initial setup was using Ubuntu 9.04.
But now with the 12.04 Update I got stuck. My System is freezing or wired errors occour.
I want to reinstall my system on a clean partition.
How can I get a list of the packages I installed in my system? I want a list with the base packages not all the dependecies, so I can install all packages on my clean install again with the correct (maybe new) dependencies.
I other words: I want to retrieve a list of all packages installed with apt-get directly. Not the ones it additionally installs with these packages.
Thanks!
