Debian Software Package Management(dpkg) in Linux

Last Updated : 23 Jul, 2025

In Linux, there are a lot of different distributions and each of these distributions has a different package type.  For example .rpm or Red hat Package Manager is used as the package in the Linux distribution. A package is the compressed version of the software.

In this article, we will go through the Debian package which is used by Ubuntu. D package or Debian Package is used to install and download the software in Debian based Linux systems. Debian files end with .deb extension.

`dpkg` (Debian Package) is a low-level package management system for Debian-based Linux distributions, such as Ubuntu. It handles the installation, configuration, upgrade, and removal of software packages. Unlike higher-level tools like `apt`, which resolve dependencies and download packages from repositories, `dpkg` directly manages individual `.deb` files, making it essential for managing local packages and performing detailed package operations.
