Bug 892771

No fc18 boot image was created after upgrade and grub2 was not updated

I was upgrading from fc17

I issued the following command

sudo fedup-cli --network 18 --debuglog fedupdebug.log --instrepo http://dl.fedoraproject.org/pub/fedora/linux/releases/test/18-Beta/Fedora/x86_64/os/

The install and packages were downloaded with no error messages, I rebooted and selected "Upgrade System", I was asked for the encryption password on the hard drive which I entered, when the progress bar screen came up I pressed escape and was left with an almost blank screen with a couple of lines. I came back to the machine after some time and it had rebooted and was at the login screen. After logging in uname -a still reported fc17, I rebooted and there was no option for fc17 in grub, I checked /boot and no fc18 image was created. 

rpm -qa | grep fc18

indicates 1682 fc18 packages were installed although not kernel

rpm -qa | grep fc17
 returns 88 packages remaining, including kernel.

I have no fedup log as I since tried to rerun it and overwrote the initial log. 
fedup now blows up with the following error
