Oh! that's something different, then. We may be looking at a bug anywhere between shim, grub, the kernel, or the installer. > So, I installed Ubuntu SecureBoot disabled, and then after enabling > SecureBoot and trying to boot Ubuntu I received "Secure Boot Violation: > Invalid signature detected. Check Secure Boot Policy in Setup". Right, that's because currently when you install on a system without Secure Boot enabled, the signed bootloader is not installed. This is related to bug #1184297, which we're working on resolving. In the meantime, after installation you can do the following: sudo apt-get install grub-efi-amd64-signed shim-signed sudo grub-install --uefi-secure-boot After running those two commands, you can reboot, re-enable SecureBoot in the firmware, and try to boot the *installed* Ubuntu under SecureBoot. It shouldn't give you a security error - though it might still fail with the same issue you saw when trying to install. Please let me know whether this lets you successfully boot the system; that will help us narrow down the real cause of this install-time bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1201257 Title: Secure Boot doesn't work with ASUS S56CB To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1201257/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
