I had the same problems as b355_etude. I upgraded from 9.04 to 9.10. After install I ran the update tool and was offered a choice to change the grub configuration to the developer's version or keep the current. I chose to view the differences. From the differences window I hit "cancel" thinking it would drop me back to the previous screen. Instead it went forward and but failed to complete the upgrade. Afterwards I ran "sudo dpkg --configure -a" through synaptic and this seems to have fixed it.
