[15:12] <vlad> I found a problem on the documentation relating to upgrading from 8.04 to 8.10. on http://www.ubuntu.com/getubuntu/upgrading using the alternate CD. The command typed into the Alt+F2 should be gksu "sh /media.cdrom0/cdromupgrade"  the same applies for kubuntu. This is where the iso was mounted so that's why the command is what I wrote and not the one that is there right now.
[15:13] <vlad> I meant /media/cdrom0/cdromupgrade
