I would like to list all the installed packages, with specific version numbers on my system. I checked out
dpkg --get-selections (How to list all installed packages) but it doesn't show me what I need. For example:
$ dpkg --get-selections apache2 apache2 install
shows that apache2 is installed, however not the version. I recently did a
apt-get upgrade so apache2.2.22-1 should be version installed (http://packages.ubuntu.com/precise-updates/apache2.2-common), but how can I show that?
