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.

The below commands are available for all the Ubuntu, Linux Mint, Elementary OS and other derivative systems.

For 32 bit systems, download and install the i386 debs. For 64 bit systems, download and install the amd64 packages:
