How to install OpenNebula Frontend on Ubuntu or Debian

OpenNebula is a powerful and flexible cloud management platform that allows you to create, manage, and deploy private and hybrid clouds. The frontend of OpenNebula provides a user-friendly interface to manage the cloud infrastructure, including virtual machines, storage, and networking.

For many organizations, OpenNebula offers a cost-effective and scalable alternative to proprietary cloud solutions. It supports a wide range of hypervisors, including KVM, VMware, and Xen, making it versatile for various deployment scenarios.

While the backend components of OpenNebula handle the actual virtualization and resource management, the frontend provides the necessary tools and interfaces for administrators and users. Installing the frontend on Ubuntu or Debian is straightforward, and this guide will walk you through the necessary steps.

1. Add the OpenNebula repository to your system's sources list.

   $ echo "deb https://downloads.opennebula.io/repo/6.6/Ubuntu/22.04/ stable opennebula" | sudo tee /etc/apt/sources.list.d/opennebula.list
   [sudo] password for user: 
   deb https://downloads.opennebula.io/repo/6.6/Ubuntu/22.04/ stable opennebula

   Ensure you choose the appropriate repository based on your Debian or Ubuntu version. Versions list are available here:
   https://downloads.opennebula.io/repo/

2. Import the OpenNebula GPG key to ensure package integrity.

   $ wget -q -O- https://downloads.opennebula.io/repo/repo2.key | sudo gpg --dearmor --yes --output /etc/apt/trusted.gpg.d/opennebula.gpg

3. Update the system package list based on the new repository.
