Now, let’s delve into the specifics of getting VS Code up and running on your Rocky Linux system.

Install Visual Studio Code on Rocky Linux 9 or 8 via DNF

Step 1: Update Rocky Linux Before VSCode Installation

Before proceeding with the Visual Studio Code installation, it is critical to update your Rocky Linux system. Updating ensures that your system has the latest security patches and is compatible with new software. Open your Terminal and enter the command:

sudo dnf upgrade --refresh

This command refreshes the repository metadata and upgrades all the packages to their latest versions.

Step 2: Set Up Visual Studio Code Repository on Rocky Linux

Visual Studio Code is not included in Rocky Linux’s default repositories. To install it, you must first add the official Microsoft repository. Begin by importing the Microsoft GPG key to authenticate the packages:

sudo rpm --import https://packages.microsoft.com/keys/microsoft.asc

Next, create a repository file for Visual Studio Code. This file guides the package manager to the correct location for downloading VSCode. Execute the command below to create this file:

printf "[vscode]\nname=packages.microsoft.com\nbaseurl=https://packages.microsoft.com/yumrepos/vscode/\nenabled=1\ngpgcheck=1\nrepo_gpgcheck=1\ngpgkey=https://packages.microsoft.com/keys/microsoft.asc\nmetadata_expire=1h" | sudo tee -a /etc/yum.repos.d/vscode.repo

When you run this command, the output will confirm that the repository file is successfully created.

Step 3: Install Visual Studio Code via DNF Command

With the repository in place, you can install Visual Studio Code. There are two versions available: the stable build and the insider build.

Installing the Stable Build

The stable build is recommended for most users due to its tested and proven reliability. Install it with:

sudo dnf install code

Installing the Insider Build

For users interested in the latest features, despite possible stability issues, the insider build is an option. Install it with:

sudo dnf install code-insiders

During the installation, you will be prompted to confirm the import of GPG keys. Ensure the key details match the following before proceeding:

Importing GPG key 0xBE1229CF:
 Userid     : "Microsoft (Release signing) <gpgsecurity@microsoft.com>"
 Fingerprint: BC52 8686 B50D 79E3 39D3 721C EB3E 94AD BE12 29CF
 From       : https://packages.microsoft.com/keys/microsoft.asc

After these steps, Visual Studio Code will be installed and ready to use on your Rocky Linux system.
