The Ubuntu Livepatch Service applies critical kernel security patches without rebooting. This is especially useful on production environments and services where downtime is disruptive.
Livepatch is free for up to 5 machines with an Ubuntu Prosubscription.
This tutorial will show you how to enable this service on your Ubuntu system.
In order to use this service, you have to attach your subscription via the Ubuntu Pro token. On public cloud marketplace Pro instances the subscription is already attached and you should skip this step.
To attach subscription, simply visit the Pro dashboard.
The dashboard will show your subscription credentials and instructions to apply them on the system. Follow the instructions and attach the system to your Ubuntu Advantage or Free subscription. It is as simple as
$ sudo pro attach [TOKEN]
Livepatch is enabled by default when attaching a subscription. You can verify your subscription status with the pro status command.
If livepatch is disabled, you can enable it with the following command:
$ sudo pro enable livepatch
You can ensure that the Livepatch service is working properly by running:
$ canonical-livepatch status --verbose
Congratulations, you now have zero downtime kernel patching on your system!
