Advanced front-end for dpkg This is Debian's next generation front-end for the dpkg package manager. It provides the apt-get utility and APT dselect method that provides a simpler, safer way to install and upgrade packages. APT features complete installation ordering, multiple source capability and several other unique features, see the Users Guide in apt-doc. This is the "X" version of apt. It can be installed in parallel to the main apt version of the OS. You probably don't want it.
