Until today, Canonical’s Kernel Livepatch service was available only for those running the Ubuntu 16.04 LTS (Xenial Xerus) operating system series, providing them with rebootless kernel upgrades. Starting today, you can use the Canonical Kernel Livepatch service on Ubuntu 14.04 LTS too. As usual, Canonical lets users to install its Kernel Livepatch service on up to three (3) computers for free, but only on systems running 64-bit Intel or AMD processors. Those who want to enable Canonical Kernel Livepatch on more than 3 machines will have to purchase the Ubuntu Advantage support package.
