How to install Kernel 4.8.7 on Ubuntu and derivative systems

Linux kernel is the essential part of any Linux operating system. It is responsible for resource allocation, low-level hardware interfaces, security, simple communications, basic file system management, and more. Written from scratch by Linus Torvalds.

Installation instructions:

Because it is very difficult to compile a Linux kernel, Canonical has packed all the kernel releases as deb packages and made them available for everybody that uses Ubuntu or Ubuntu-based systems, via its kernel.ubuntu.com repository.
