Installing a DEB Package

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.

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

Now that htop is installed, we can run it with the htop command:
```
htop
```
This utility shows us system load and running processes.
Press Q to exit the application.

Remove the `htop` Package

Use dpkg to remove the htop package:
```
sudo dpkg --remove htop
```
