Install Linux Packages from Remote Repositories (Fedora & RHEL Edition)

In this challenge, you'll practice one of the key Linux skills - installing packages from remote repositories.

Task 1: Install a package from the official repository

tree is a handy command-line utility that displays directory structures in a tree-like format.

The tree package is available in Fedora's official package repository - installing it is just one command away.

Hint 1

On Fedora and RHEL systems, dnf is the go-to tool for installing software.

Hint 2

Unlike apt-get on Debian and Ubuntu, dnf doesn't require you to update the package list before installing a package, so you can proceed directly to dnf install.

Getting Permission denied? Use sudo.

Task 2: Install a package from a third-party repository

Not all software is available in the distribution's official repositories. Many projects maintain their own RPM repositories that you can add to your system.

Install GitHub CLI (gh) - a command-line tool for working with GitHub from the terminal.

This package is not in Fedora's official repositories, so you'll need to add GitHub's own repository first.

Hint 3

The general process for adding a third-party DNF repository is:

  1. Download the repository's .repo configuration file into /etc/yum.repos.d/
  2. Install the package with dnf install

Unlike APT, DNF repository files typically include the GPG key URL directly in the .repo file, so there's no separate key import step.

Hint 4

Visit the project's installation docs for detailed instructions.

How to Author Challenges on iximiuz Labs

Instead of providing a subpar online editing experience, iximiuz Labs offers a helper CLI tool called labctl, allowing you to use your favorite text editor (or a full-featured IDE) to write content from the comfort of your local machine.

Install labctl CLI

curl -sf https://labs.iximiuz.com/cli/install.sh | sh

This will download and install the latest version of the labctl CLI. You only need to do this once per workstation.

Authorize labctl

labctl auth login

This will open a browser window asking you to authorize labctl to access your account. You need to do it after a fresh install of labctl and repeat it whenever the auth session expires.

Pull challenge content

labctl content pull challenge linux-install-packages-fedora-rhel

This will create a local copy of the challenge content in a directory named linux-install-packages-fedora-rhel. You only need to do this once per challenge.

Stream your changes

labctl content push -fw challenge linux-install-packages-fedora-rhel

Run this command in a separate terminal to continuously upload your changes to the server while editing the challenge in your favorite text editor or IDE.

You can also use labctl to create, list, and delete your content. Learn more about the available commands: labctl content --help
