I had the same problem when upgrading 14.04 to 14.10 on VirtualBox 4.3.12 r93733, running on Windows 7/x64.
To fix this: 1. Press Shift key during booting to get Grub's prompt 2. Choose Advanced options for Ubuntu from the menu 3. Choose Ubuntu, with Linux 3.16.0-24-generic (recovery mode) 4. Choose dpkg: Repair broken packages 5. Choose resume; the system goes up fine (and this persists for the next reboot, too)! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1386775 Title: After upgrading Ubuntu 14.04 to 14.10, boot process halts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1386775/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
