Challenge, Easy,  on  Linux

Install Linux Packages from Remote Repositories (Debian & Ubuntu Edition)

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

Task 0: Update the package list

First, you need to update the package list to ensure you have the latest information about the packages available in the repositories.

Hint 1

On Debian and Ubuntu systems, apt-get is the go-to tool for installing software. Run man apt-get and try finding the relevant command to update the package list.

Hint 2

Getting Permission denied error when updating the package list? Make sure you have the necessary permissions to manage packages on your system (e.g. use sudo or run the command as root).

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 Ubuntu's official package repository - installing it is just one command away.

Hint 3

It's a simple one. Use apt-get install followed by the package name.

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 APT 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 Ubuntu's official repositories, so you'll need to add GitHub's own repository first.

Hint 4

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

  1. Download the repository's GPG signing key
  2. Add the repository to your APT sources
  3. Run apt-get update to fetch the new repository's package list
  4. Install the package with apt-get install

Profit!

Hint 5

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-debian-ubuntu

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

Stream your changes

labctl content push -fw challenge linux-install-packages-debian-ubuntu

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
