APT - Advanced Package Tool
● The recommended way to manage software packages on Ubuntu and other Debian
based distributions is using apt.
● In the newest versions of Ubuntu the apt-get and apt-cache tools were merged into a
single command simply called apt.
● Unlike dpkg, apt does not understand .deb files. It works with packages that are
downloaded from repositories and calls dpkg directly after downloading the .deb
archives.
● An APT repository is a web server which contains a collection of packages with
metadata that is readable by the apt tool.
● A special kind of repository hosted on servers like Launchpad are PPAs.
