Canonical Livepatch is a free and commercial solution for applying Linux kernel updates without rebooting your Ubuntu computer. Initially designed for the Ubuntu 16.04 LTS (Xenial Xerus) operating system series, Canonical’s kernel livepatch service is coming in an easier-to-use form in Ubuntu 18.04 LTS, due for release on April 26. The Software & Updates utility found in the default Ubuntu installation now integrates the Canonical Livepatch service in the Updates tab, but, to use it, you’ll have to create an Ubuntu SSO (Single Sign-On) account and login with it by clicking on the “Sign In” button.
