Ubuntu 14.04 is about to reach the end of its life, and Canonical officially announced today the Extended Security Maintenance (ESM) program. Canonical said: “Extended Security Maintenance (ESM) was introduced for Ubuntu 12.04 LTS as a way to extend the availability of critical and important security patches beyond the nominal End of Life date of Ubuntu 12.04. Organisations use ESM to address security compliance concerns while they manage the upgrade process to newer versions of Ubuntu under full support. The ability to plan application upgrades in a failsafe environment continues to be cited as the main value for adoption of ESM. With the End of Life of Ubuntu 14.04 LTS in April 2019, and to support the planning efforts of developers worldwide, Canonical is announcing the availability of ESM for Ubuntu 14.04.”.
