Keeping your Linux systems up-to-date is crucial for security, stability, and accessing new features. However, manually updating packages can be a time-consuming task. Fortunately, several Linux distributions offer tools to automate this process, among which DNF Automatic is prominently used in RHEL (Red Hat Enterprise Linux). In this guide, we will explore how to set up DNF Automatic on RHEL and also briefly discuss automation tools for other package managers like apt for Debian/Ubuntu-based systems, and zypper for openSUSE. DNF Automatic is an extension of DNF, the package manager used in Fedora, RHEL, and CentOS. It allows administrators to schedule and automatically manage package updates.

Managing a Linux system often involves needing to download packages and update your system using tools like apt, dnf, or zypper. However, in corporate environments or certain geographical locations, your network might require you to use a proxy server to access external network resources. This can be a bit confusing when you first encounter it, but no worries; setting up a proxy for updates and downloads from the command line is straightforward once you know where to make the right adjustments. Before diving into configurations, let's quickly understand what a proxy server does. A proxy acts as an intermediary for requests from clients seeking resources from other servers.

When it comes to managing packages in Linux-based systems, understanding how to synchronize and update software across different distributions is crucial for system administrators and developers alike. Linux distributions often use unique package management systems which can make uniform updates seem challenging. In this article, we will delve into how to handle package updates efficiently across systems that utilize apt (Debian, Ubuntu), dnf (Fedora), and zypper (openSUSE). Before we jump into synchronization, let’s briefly outline what each package manager is primarily used for: Apt (Advanced Package Tool): Used by Debian and its derivatives like Ubuntu. It handles the installation and removal of software.
