[Ubuntu-ma] Updates sadda3ni 3la upgrade 10.04.

[Nordin]

Salam alikoum my brothers,

I installed Xubuntu karmic (9.10) on an old laptop, which is working 
well (but a bit slow).
Anyway, when doing software update I get a message about upgrading 
Ubuntu 10.04. But I know that if I upgrade to 10.04 my laptop won't boot 
anymore and I don't want to find out what's wrong.

Is there a way to de-activate that message?
