About this Hands-on Lab

In this hands-on lab, we will install a DEB package on an Ubuntu system. On Debian-based Linux distributions, we can install deb packages using the `dpkg` command.

This gives us the hands on experience of installing and removing deb packages directly, without the use of a more comprehensive package manager like apt.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Install the `htop` DEB

Note: Please wait an extra 6-7 minutes before starting the lab to make sure the lock on dpkg has been released.

  1. The htop DEB package is located in the cloud_user home directory. In order to install the package, we need to elevate our permissions.

    Use the following command to install the package (Note: If you receive a dpkg lock error, you can wait till the boot time scripts have finished, then proceed):

    sudo dpkg -i htop_2.0.2-1_amd64.deb
Run the `htop` Application
  1. Now that htop is installed, we can run it with the htop command:

    This utility shows us system load and running processes.

  2. Press Q to exit the application.
Remove the `htop` Package
  1. Use dpkg to remove the htop package:
    sudo dpkg --remove htop

Additional Resources

A DEB file has been provided for you in the cloud_user home directory at /home/cloud_user.

Follow along with the video as we install the DEB package, run the new utility it provides, and then remove the package.

Note: Please wait about 6-7 minutes before starting the lab to make sure the lab has fully provisioned.
