Recover a Kubuntu Focus Installation

For whatever reason, you might find yourself in a situation where your system isn't booting. Rather than doing a Clean Install, you may be able to recover your system.

Please read the disclaimer before proceeding. This solution is updated regularly. If you have suggestions or requests, please share your thoughts on the Guided Solution Authorship Form.

Background

As opposed to the Clean Install method, it may be more worthwhile to recover your installation. A Clean Install will require you to reinstall all applications you had before, which may be time-consuming in and of itself. Using recovery media to recover your installation might be preferable.

Do keep in mind, however, that this process may be even more time-consuming than a simple Clean Install, however the method may be more desirable as you would not have to set-up your environment again.

There are several reasons why your system may have failed, including an interrupted package upgrade, a failed update to the Initial RAM disk (which is part of the boot process), or a full /boot directory due to too many kernels. Whatever the reason, this guide is designed to get you back up and running and should be used prior to the Clean Install method mentioned above.
