Debian GNU/Linux is the backbone of several popular Linux distributions like Knoppix, Kali, Ubuntu, Mint, and more. One of its strongest features is its robust package management system, which makes installing, removing, and managing software a breeze.
Debian and its derivatives use a variety of package managers such as dpkg, apt, apt-get, aptitude, synaptic, tasksel, dselect, dpkg-deb, and dpkg-split. each serving a different purpose.
