Much of why Debian is a strong Linux distribution comes from the core of Debian namely its package management. Everything in Debian – every application, every component – everything – is built into a package, and then that package is installed onto your system (either by the Installer, or by you).

There are over 29 thousand software packages available for Debian – everything from the Linux kernel to games.

What is APT?

APT (for Advanced Package Tool) is a set of tools for managing Debian packages, and therefore the applications installed on your Debian system. APT makes it possible to:

  • Install applications
  • Remove applications
  • Keep your applications up to date
  • And much more...

APT resolves dependency problems and retrieves requested packages. APT delegates the actual installation and removal of packages to dpkg. APT is primarily used by commandline tools, but

  • there are many GUI tools to let you use APT without having to touch the command line.

  • tools like aptitude can interact with APT via both commandline and TUI interfaces.
