This is a follow-up to the End of Life warning sent last month to confirm that as of today (April 30, 2015), Ubuntu 10.04 is no longer supported. No more package updates will be accepted to 10.04, and it will be archived to old-releases.ubuntu.com in the coming weeks.
The original End of Life warning follows, with upgrade instructions:
Ubuntu announced its 10.04 (Lucid Lynx) release almost 5 years ago, on April 29, 2010. 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 10.04 will reach end of life on Thursday, April 30th. At that time, Ubuntu Security Notices will no longer include information or updated packages for Ubuntu 10.04.
The supported upgrade path from Ubuntu 10.04 is via Ubuntu 12.04. Users are encouraged to evaluate and upgrade to our latest 14.04 LTS release via 12.04. Instructions and caveats for the upgrades may be found at https://help.ubuntu.com/community/PreciseUpgrades and https://help.ubuntu.com/community/TrustyUpgrades. Ubuntu 12.04 and 14.04 continue to be actively supported with security updates and select high-impact bug fixes. All announcements of official security updates for Ubuntu releases are sent to the ubuntu-security-announce mailing list, information about which may be found at https://lists.ubuntu.com/mailman/listinfo/ubuntu-security-announce.
Since its launch in October 2004 Ubuntu has become one of the most highly regarded Linux distributions with millions of users in homes, schools, businesses and governments around the world. Ubuntu is Open Source software, costs nothing to download, and users are free to customise or alter their software in order to meet their needs.
