Debian GNU/Linux provides several package-management tools, primarily intended to facilitate the building, installation, and management of binary packages. In addition, the tools described here also work on other Debian-based systems such as Ubuntu, Xandros, Knoppix, and numerous others.
Debian package names generally end in .deb. The Debian package-management tools we describe include the apt commands, aptitude, dpkg, dpkg-deb, dselect, and synaptic. Each of these tools is described in detail in Debian Package Manager Command Summary in Debian Package Manager Command Summary.
