Ubuntu Core support duration¶
The support period for Ubuntu Core follows the Long Term Support (LTS) model adopted by all major releases of Ubuntu.
An optional Legacy Support can be added to expand security maintenance (ESM) for an additional 2 years, resulting in 12 years of coverage overall for newer releases. See Expanded Security Maintenance for Ubuntu and open source for further details.
