Installing DNF in RHEL(Red Hat Enterprise Linux)

DNF is installed in RHEL distributions as the default package manager. To check the version of ‘dnf’ or if it is preinstalled go to Step 3 directly. However, if you need to reinstall the package use the following steps :

Step 1: Open the terminal using the keys CTRL+ALT+T or by searching the terminal in the start menu.

Step 2: We can use the ‘yum’ package manager to install ‘dnf’:

sudo yum install dnf

You need to enter your password to grant sudo permission.

Step 3: To verify if it is installed and the version of ‘dnf’. Enter the following command:

dnf --version

Linux offers several package managers for software installation, updates, and maintenance. In Linux, every distribution comes with a package manager by default. The Debian distribution comes with APT(Advanced Package Tool), Red Hat, and its derivatives such as CentOS and Fedora use YUM package management.

However, there may be cases when you need to use different package managers. In this article, we’ll cover the installation and setup of three prominent package managers which are:

• DPKG: DPKG is a base package management system used in the Debian Linux family, it is used to install, remove, store, and provide information about ‘.deb’ packages. ‘dpkg’ is a low-level package manager and is used in combination with higher level package managers like ‘apt’ or ‘apt-get’, which provide more user-friendly interfaces for package management.
• APT: APT is a powerful tool used in Debian-based distributions such as Ubuntu, Linux Mint, and many others. APT makes the process of installing, updating, and removing software packages simple. APT manages dependencies by itself and ensures all the packages are installed when you install a new package.
• DNF: DNF stands for ‘Dandified YUM’ and is the default package manager of Red Hat-based Linux distributions. It is the evolution of the YUM(Yellowdog Updater, Modified) package manager which improves performance, dependency resolution, and usability.
