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! ** Changed in: apt (Ubuntu) Importance: Undecided => High ** Changed in: apt (Ubuntu) Status: New => Triaged -- Ubuntu extras repository prevents other updates https://bugs.launchpad.net/bugs/678196 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
