The problem is that you are using a demonstration frontend for the apt library, instead of a real package manager. aptitude or even dselect will display packages that are not in the archive as "obsolete" or "local", making it easy to tell when you have something outdated. -- see shy jo
Seven reasons why you should be using aptitude instead of apt-get. 1. aptitude can look just like apt-get If you run 'aptitude update' or 'aptitude upgrade' or 'aptitude install', it looks and works just like apt-get, with a few enhancements. So there is no learning curve. 2. aptitude sanely handles recommends A long-standing failure of apt-get has been its lack of support for the Recommends relationship. Which is a problem because many packages in Debian rely on Recommends to pull in software that the average user generally uses with the package. This is a not uncommon cause of trouble, even though apt-get recently became able to at least mention recommended packages, it's easy to miss its warnings. Aptitude supports Recommends by default, and can be confgigured to support Suggests too. It even supports installing recommended packages when used in command-line mode. 3. aptitude tracks automatically installed packages Stop worrying about pruning unused libraries and support packages from your system. If you use aptitude to install everything, it will keep track of what packages are pulled in by dependencies alone, and remove those packages when they are no longer needed. 4. use aptitude as a normal user and avoid hosing your system Maybe you didn't know that you can run aptitude in gui mode as a regular user. Make any changes you'd like to try out. If you get into a real mess, you can hit 'q' and exit, your changes will not be saved. (aptitude also lets you use ctrl-u to undo changes). Since it's running as a normal user, you cannot hose your system until you tell aptitude to do something, at which point it will prompt you for your root password. 5. aptitude has a powerful UI and searching capabilities Between aptitude's categorical browser and its great support for mutt-style filtering and searching of packages by name, description, maintainer, dependencies, etc, you should be able to find packages faster than ever before using aptitude. 6. aptitude makes it easy to keep track of obsolete software If Debian stops distributing a package, apt will leave it on your system indefinitly, with no warnings, and no upgrades. Aptitude lists such packages in its "Obsolete and Locally Created Packages" section, so you can be informed of the problem and do something about it. 7. aptitude has an interface to the Debian task system Aptitude lets you use Debian's task system as it was designed to be used. You can browse the available tasks, select a task for install, and then dig into it and de-select parts of the task that you don't want. apt-get has no support for tasks, and aptitude is better even than special purpose tools like tasksel.
