Version 12.04 of the Ubuntu distribution was a long term support (LTS) release and received five years of support and security fixes. Adam Conrad has sent out a reminder that Ubuntu 12.04 will reach the end of its supported life on April 28, 2017. People still running Ubuntu 12.04 are encouraged to either perform live upgrades to version 14.04 or install Ubuntu 16.04, both of which are also long term support releases. "Ubuntu announced its 12.04 (Precise Pangolin) release almost 5 years ago, on April 26, 2012. As with the earlier LTS releases, Ubuntu committed to ongoing security and critical fixes for a period of 5 years. The support period is now nearing its end and Ubuntu 12.04 will reach end of life on Friday, April 28th. At that time, Ubuntu Security Notices will no longer include information or updated packages for Ubuntu 12.04. The supported upgrade path from Ubuntu 12.04 is via Ubuntu 14.04. Users are encouraged to evaluate and upgrade to our latest 16.04 LTS release via 14.04." People who wish to continue receiving security updates for Ubuntu 12.04 can purchase a extended security maintenance (ESM) package from Canonical. Dustin Kirkland provides more information on the ESM offer in a mailing list post.
