Resetting to Triaged; we're fixing this, but I can't realistically say that I'm actively working on it at the moment. It involves moving to a new signing key before we can stop grub from falling back to 'linux' when 'linuxefi' validation fails.
This has nothing to do with nvidia-prime or loading whatever drivers -- drivers still load normally, this changes nothing at all but the fact that on a failure to validate the kernel image, grub will still load the badly-signed kernel rather than reporting an error and kicking the user back to the GRUB menu. ** Changed in: grub2 (Ubuntu) Status: In Progress => Triaged ** Changed in: grub2 (Ubuntu) Importance: Wishlist => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1401532 Title: GRUB's Secure Boot implementation loads unsigned kernel without warning To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1401532/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
