Comment 33 for bug 855793

> Does this happen every time, or are there instances where an upgrade will work? Could anyone please comment if they were successful in upgrading after a first install?

I installed Kubuntu 11.10 release four different ways (using both alt installer and Live CD) and this error happened to me every time on each different fresh installation. It also happens if you try it in the Live CD. So it appears it happens every time.
