Comment 3 for bug 678196

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here.

I have attempted to upgrade daily using "sudo apt-get update" and "sudo apt-get dist-upgrade" for about a week. This effectively blocks all updates. Using update-manager also fails. Commenting out extras in /etc/apt/sources.list shows 225 upgrades on this system.

Thanks for taking the time to make Ubuntu better!
