Comment 28 for bug 430272

I booted from a live cd and ran apt-get update; apt-get upgrade, but the system reboots after doing this:

Setting up upstart (0.6.3-3)

I've done it three times now, and any use of dpkg or apt results in the message:

E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct this problem

Which, if I do, causes upstart to run its post-install scripts and reboot the system.

Any ideas?
