Linux continues to be a powerful operating system beloved by developers, sysadmins, and tech enthusiasts for its flexibility, security, and robust community support. One of the core strengths of Linux is the ease of managing applications through package managers. This guide will delve into the specifics of managing packages in Linux distributions that use APT (such as Debian and Ubuntu), DNF (used in distributions like Fedora and CentOS Stream), and Zypper (primarily used by openSUSE). A package manager is a tool that helps manage software packages within a Linux system. This includes installing, updating, configuring, and removing software packages.

The change in popularity of open-source operating systems, particularly in the wake of Red Hat's decision to shift CentOS to an upstream provider (CentOS Stream), has been significant. This decision fundamentally altered the landscape of enterprise Linux distributions and led to the rise of alternative distributions such as AlmaLinux and Rocky Linux. Here's a closer look at the changes in popularity, the rationale behind them, and why people should consider switching to distributions like AlmaLinux or Rocky Linux.
