What are Livepatch tiers?

Livepatch delivers patches to “tiers”. A tier is a target audience for the delivery of a patch. Your tier depends on whether you have a free or paid subscription to Ubuntu Pro. The differences are outlined below.

Tier Description
Internal For internal Canonical use. Updates are first tested then applied across Canonical infrastructure to decrease the odds of a faulty patch making it to customer machines.
Updates For free users of Ubuntu Pro. Patches are delivered to these machines next.
Stable For paid users of Ubuntu Pro. Patches are delivered to these machines last.

Our kernel team closely monitors the patch health within internal before promoting to updates and further monitoring is done before promoting the patch to stable.

For finer-grained control over patch roll-out take a look at Livepatch On-Prem.
