People who do not wish to disconnect their projects from the network (reboot the device) no longer have to worry about updates to your system. With this wonderful function, the server will always remain up to date. Updates are installed promptly and quickly, the headache will considerably less.

How to enable Canonical Livepatch on Ubuntu 18.04 LTS

On older LTS versions (14.04 and 16.04) this function is enabled via the command line.

Ubuntu 18.04 LTS is still easier – the feature can be enabled through a special window, which is available in the settings for Software & Updates. It is worth noting that you must be logged in to Ubuntu One, because Canonical imposes some restrictions on the use of this great feature. No more than 3 PCs can use Canonical Livepatch.

If you will be essential to use the function on a larger number of devices will have to license Ubuntu Advantage. Although, in principle, nobody forbids you from just making another account Ubuntu One. Or use the command line, for example.
