Advanced Package Tool (APT) is a free-software user interface that works with core libraries to handle the installation and removal of software on Debian and Debian-based Linux distributions. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code.
