Bug Description
On the update of grub-efi-amd64, it's now warning about unsigned kernels, which it was not doing before, and failing. However, before this update, the unsigned kernels were booting properly with Secure Boot enabled. I don't know what would make them unbootable now. The following message appears on upgrade:
┌─────
│ │
│ Cannot upgrade Secure Boot enforcement policy due to unsigned kernels │
│ │
│ Your system has UEFI Secure Boot enabled in firmware, and the following │
│ kernels present on your system are unsigned: │
│ │
│ 4.17.18-
│ 4.17.17-
│ │
│ │
│ These kernels cannot be verified under Secure Boot. To ensure your │
│ system remains bootable, GRUB will not be upgraded on your disk until │
│ these kernels are removed or replaced with signed kernels. │
Using the Ubuntu's default kernel is not an option to me, as it has bugs that weren't solved and make my notebook fail to boot.
