Questions tagged [apt]

APT, the Advanced Packaging Tool, is Debian's high-level package management system. It is also used by several other Linux-based and Debian-based operating systems.

The Advanced Packaging Tool, or APT, is a free user interface that works with core libraries to handle the installation and removal of software on the Debian GNU/Linux distribution and its variants. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from binary files or by compiling source code.
