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.
