Installation of a New Package Manager on Linux
Installation of different packages differs in steps at different linux distributions. Let’s look at the installation of three different package managers one by one:
Installing DPKG in Debian
Package managers are core components of linux systems, and are pre-installed. To check the version of ‘dpkg’ or if it is preinstalled go to Step 4 directly. However, if you need to reinstall follow the steps given below:
Step 1: Open the terminal using the keys CTRL+ALT+T or by searching the terminal in the start menu.
Step 2: To install ‘dpkg’ in Debian, we are using ‘apt-get’ which is another package manager. In the first step, we will update the apt-get to ensure that our local package database gets synchronized with the latest updates.
sudo apt-get update
After entering the above command you need to enter the administrator password to provide root user privileges.
‘sudo’Debian: This command allows users with permission to execute commands with superuser(root) privileges.
‘apt-get’: It is a command line package management tool in Debian-based systems. It is used for installing, removing, or updating various packages.
Step 3: To reinstall the ‘dpkg’ package in Debian, we need to enter the following command in the terminal:
sudo apt --reinstall install dpkg
The above command tells ‘apt-get’ to reinstall the ‘dpkg’ package.
Step 3: To check if the package is installed, and the version of the package. Enter the following command:
dpkg --version
How to Install a New Package Manager in Linux
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.
