Which package management tool does Debian use to manage software packages?

Debian uses APT (Advanced Package Tool) as its primary package management tool to manage software packages. APT is a command-line tool that provides a range of commands for searching, installing, upgrading, and removing software packages. APT also supports dependency resolution and automatic installation of required dependencies. APT can be used in conjunction with Debian’s software repositories, allowing users to easily access the latest software packages via the network.
