I also experience this bug on 10.10 on 2 different computers.
It's a big issue because I thought these computers would have security updates until October 2012.
And I suddenly realise their support will end up ... next month (April 2012)...
It should be noted that this help screen is half translated in French. In particular, the first sentence that contains wrong information is still in English :
"You are using Ubuntu 11.04 - the Natty Narwhal - released in April 2011 and supported until October 2012.
