Thanks for taking the time to report this bug and helping to make Ubuntu better. Could you please add the log files from '/var/log/dist-upgrade/' to this bugreport as attachments to your bug report? Thanks in advance.

I got this same error as well, and now its saying the upgrade must stop, and its offering to run recovery

logs attached here...

i got X to come back up, but for some reason it can't detect my monitor anymore, and even though i tell it to use the nvidia prop driver, it does not, it tries, and just failed, so i pick the nv driver and go from there. I manually removed nvidia-glx and added it back in with synaptic, this re-installed the restricted drivers and all that...

my issue is, my upgrade to gibbon failed... and i can't get it to continue where it left off, OR to do the whole thing all over again... can i trick ubuntu into thinking i am a feisty system again and do the upgrade?

Thanks guys for the logs! I am confirming this bug now.
