Ubuntu announced its 14.10 (Utopic Unicorn) release almost 9 months ago, on October 23, 2014. As a non-LTS release, 14.10 has a 9-month month support cycle and, as such, the support period is now nearing its end and Ubuntu 14.10 will reach end of life on Thursday, July 23rd. At that time, Ubuntu Security Notices will no longer include information or updated packages for Ubuntu 14.10.
The supported upgrade path from Ubuntu 14.10 is via Ubuntu 15.04. Instructions and caveats for the upgrade may be found at:
Ubuntu 15.04 continues to be actively supported with security updates and select high-impact bug fixes. Announcements of security updates for Ubuntu releases are sent to the ubuntu-security-announce mailing list, information about which may be found at:
