Kernel Livepatch Service for Ubuntu 14.04

Kernel Livepatch Service is especially important for computers that must be running continuously without the possibility of restarting. Users are in luck because they can already use this service on three systems including the 32-bit and 64-bit versions of Ubuntu 14.04 LTS, in addition to of course the latest LTS Ubuntu 16.04. If you want to use it in more than three systems, you must contact Canonical.

To activate the Kernel Livepatch Service in Ubuntu 14.04 LTS, just follow these steps:

Install snapd:

sudo apt update && sudo apt install snapd

Restart the system using the Linux 4.4 Kernel if you were using a previous version, if you are already in this version or higher you can go to the next step.

Go to https://ubuntu.com/livepatch and ask for your livepatch token, for example:

Install canonical-livepatch:

sudo snap install canonical-livepatch

Activate your account with the livepatch token obtained previously, for example

sudo canonical-livepatch enable d3b07384d113edec49eaa6238ad5ff00

You already have everything done, you can check the status with:

$ canonical-livepatch status kernel: 4.4.0-70.91 ~ 14.04.1-generic fully-patched: true version: "21.1"

With this you can always have the kernel of your Ubuntu system updated without the need to restart.
