How To Install Emacs on AlmaLinux 9

In this tutorial, we will show you how to install Emacs on AlmaLinux 9. Emacs, the legendary text editor, has been a staple in the Linux community for decades. Its powerful features, extensibility, and versatility make it a favorite among developers, writers, and power users alike.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of GNU Emacs on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux or RHEL-based.

Prerequisites

• A server running one of the following operating systems: AlmaLinux 9.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for Emacs.
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Emacs on AlmaLinux 9

Step 1. Updating the System.

To ensure a successful installation and optimal performance of Emacs, it is crucial to update your AlmaLinux 9 system before proceeding with the installation. Updating the system helps resolve any potential dependency issues and ensures that you have access to the latest security patches and bug fixes. To update your system, open the terminal and run the following commands:

sudo dnf clean all
sudo dnf update

This command will remove any cached package data and update your system with the latest available packages and security patches.

After updating your system, it’s a good practice to verify that the process was completed successfully. You can do this by running:

sudo dnf list updates

Step 2. Installing Emacs on AlmaLinux 9.

Emacs is renowned for its extensibility and powerful features. To install it on your AlmaLinux 9 system, follow these steps:

sudo dnf install emacs

AlmaLinux will prompt you to confirm the installation by entering ‘y.’ Press ‘y‘ and then ‘Enter‘ to proceed.

This command will download and install Emacs, along with any necessary dependencies. Once the installation is complete, you can confirm the installation by checking the Emacs version:

emacs --version

To start Emacs for the first time, simply type:

emacs
