The analysis here is incorrect. The previous SRU affected the generation of /boot/grub/grub.cfg, but it did *not* touch /etc/default/grub, which is what the ucf prompt on upgrade is about. Reverting the SRU not only won't fix the issue, it most likely will cause the same issue *again* for affected users on upgrade.
I'm looking now to try to figure out why ucf is prompting here. It *shouldn't*, because there are no changes to the ucf template between the old and new versions of the package; so the fact that there is a prompt points to a bug in the ucf invocation, a bug in ucf, or a bug in the AMI having messed with ucf's internals inappropriately. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1009294 Title: Grub update breaks automated dist-upgrade scripts on AMI images To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1009294/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
