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
Alternatively go to Software and Updates >> Livepatch and turn the slider to off.
Another possibility is to do the following:
man uato see what the Ubuntu Advanced services are;ua statusto see how your settings are configured;sudo ua disable livepatchand thenua statusfor control.
