Support for Ubuntu Server 6.06 ends in June
With the fifth anniversary of Ubuntu Server 6.06 LTS arriving on Wednesday, 1 June 2011, the "Dapper Drake" edition of Ubuntu Linux will come to the end of its life and no more security updates or critical fixes will be issued for it. Users who are still running Ubuntu 6.06 are advised by Ubuntu's release manager, Kate Stewart, to upgrade to Ubuntu 8.04 LTS (Hardy Heron) as the officially supported upgrade path. Instructions for performing the upgrade are available on the Ubuntu documentation site.
Dapper Drake was the first Ubuntu release with Long Term Support (LTS) status. LTS releases provide critical fixes and security updates for the server edition for five years and for the desktop edition for three years; Dapper Drake's desktop support ended two years ago. The desktop edition of Ubutunu 8.04 LTS will reach its end of life in May but the server version will continue to be supported for two further years. For non-LTS versions, support ends after 18 months for all versions, so, for example, at the end of this month on 29 April, support for Ubuntu 9.10 will end.
