Canonical will continue to provide security updates to Ubuntu 12.04 clients on its Ubuntu Advantage service.
Ubuntu 12.04 (Precise Pangolin), a long-term support edition of the operating system, released on 26 April 2012 and will reach its end of life on 25 April 2017.
Customers who want continued security updates for Pangolin can receive them through Ubuntu 12.04 Extended Security Maintenance (ESM).
This will provide security fixes for the kernel and essential user space packages in Ubuntu 12.04, said Canonical.
The updates are delivered in a secure, private archive available to Ubuntu Advantage customers.
Ubuntu 12.04 LTS users are encouraged to upgrade to Ubuntu 14.04 LTS or Ubuntu 16.04 LTS.
Ubuntu Advantage customers can get ESM credentials by filing a support request at support.canonical.com.
