While working to verify some packages in Ubuntu 12.04 had backport patches installed properly I needed to list installed package versions. To do this you can install a package called apt-show-versions which will allow you to list all installed packages and their versions with ease. This likely works on most Ubuntu versions but was tested on Ubuntu 12.04 also know as Precise Pangolin and Ubuntu 12.10 also known as Quantal Quetzal. Follow the instructions below to install apt-show-versions and then list all installed packages and their versions.
Install apt-show-versions On Ubuntu To List Package Versions:
- root@dev:/etc/apache2# apt-get install apt-show-versions

List Single Package Version Ubuntu 12.04:
- root@dev:/etc/apache2# apt-show-versions | grep apache2\/
- apache2/quantal-security uptodate 2.2.22-6ubuntu2.3
- root@dev:/etc/apache2#
