Canonical offers livepatching for its kernel, where every home user can get three licenses.

However, I'd like to know how I can de-register a machine from my license. If I get rid of a computer, I'd rather not lose one of my three licenses.

Is there a formalized procedure to deactivate a machine's license and transfer it to a new machine?


Yes, just run

sudo snap run canonical-livepatch disable

    And this actually frees up one of the livepatch licenses again? I've dealt with software where disabling things doesn't give you the license back, so I want to verify with Ubuntu.

    I’ve done this on more than three machines(the limit) and it worked fine. Nov 22 '17 at 16:40

    Do I have to run this on the old machine? What if it was a cloud instance and it's deleted. How do I reset all registered machines? Thanks

  • @Houman did you ever find the answer to your follow-up question about cloud instances?

    @DGinzberg I'm no longer using Ubuntu. But I remember that only the last three activated devices were kept. Hence older devices simply fall off the cliff and get removed.

Alternatively go to Software and Updates >> Livepatch and turn the slider to off.


Another possibility is to do the following:

  • Check out man ua to see what the Ubuntu Advanced services are;
  • ua status to see how your settings are configured;
  • sudo ua disable livepatch and then ua status for control.
