I faced this when upgrading Ubuntu Desktop from 13.10 to 14.04 (via update-manager).
Following workaround worked fine for me: I killed the update-grub process. That resumed the installer and it finally managed to complete successfully. I also did a manual run of `update-grub` which succeeded without any freezing or other issues. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1285312 Title: Setting up mdadm (3.2.5-5ubuntu3) freezes at Found kernel: when upgrading from Saucy to Trusty To manage notifications about this bug go to: https://bugs.launchpad.net/grub/+bug/1285312/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
