Linux is known for its versatility and flexibility. One significant advantage that Linux users have over other operating system users is the ability to access, manage and install software using a package manager. To put it simply, a package manager is a tool that helps you maintain, install, and manage the software packages installed on your Linux system.

There are three popular package managers for Linux: APT, DNF, and YUM. In this article, we will compare the three package managers, explain their differences, their strengths and weaknesses.

APT (Advance Package Tool)

APT is the package manager used in Debian-based operating systems, such as Ubuntu, and their derivative distributions. APT can install, update, and remove packages. It uses a command-line interface, though there are front-ends like synaptic for users who prefer a graphical interface. APT is renowned for its versatile dependency resolution system that ensures that all the dependencies of a package are met when it is installed. APT’s greatest strength is its reliability, allowing users to upgrade or install packages without breaking their system.

DNF (Dandified Yum)

DNF is the package management tool used in Fedora, RHEL (Red Hat Enterprise Linux), and CentOS. DNF command-line interface is similar to APT but offers a few unique features. One of these is the ability to track and install package dependencies from multiple repositories and manage conflicting packages. Furthermore, DNF offers faster dependency resolution compared to YUM by utilizing advanced algorithms and techniques. DNF is an improved and advanced version of YUM, with added capabilities, better performance, and integration of the library.

YUM (Yellowdog Updater, Modified)

YUM is the default package manager for RHEL, CentOS, and Fedora till version 21. It uses a command-line interface to manage packages and has a straightforward syntax for executing its commands. Like APT, YUM can install, update, and remove packages, but it is slower in resolving package dependencies than the other two. However, YUM is still reliable and provides seamless upgrades that do not break the system. One of YUM’s greatest strengths is the ability to install RPM packages- a package format used on Red Hat-based Linux distributions.
