Ubuntu Core support duration¶
Ubuntu Core follows our Long Term Support (LTS) model. Each release includes 10 years of security maintenance.
A Legacy add-on can be optionally purchased to cover an additional 5 years of security maintenance, resulting in 15 years of coverage overall. The Legacy add-on is available through an Ubuntu Pro subscription.
