Ubuntu 6.06 LTS (Dapper Drake) has reached it's end of life. Here the announcement:



[qutoe]Ubuntu announced its 6.06 Server release 5 years ago, on June 1,
2006. For the LTS Server releases, Ubuntu committed to ongoing
security and critical fixes for a period of 5 years. The maintenance
period has now ended for Ubuntu 6.06 LTS Server.

Ubuntu 6.06 LTS was a major milestone for the Ubuntu project, being the
first long-term release. Its retirement evokes memories of Ubuntu as a
younger project, and reminds us of all that we've accomplished together in
the five years since we released the "Dapper Drake".

Thanks to everyone who helped make it happen!
