Public bug reported: After updating following packages system can't boot with secureboot enabled:
shim from 0.9+1465500757.14a5905.is.0.8-0ubuntu3 to 0.9+1474479173.6c180c6-0ubuntu1 grub-efi-amd64 from 2.02~beta2-36ubuntu11 to 2.02~beta2-36ubuntu11.1 grub-efi-amd64-signed from 1.74+2.02~beta2-36ubuntu11 to 1.74.1+2.02~beta2-36ubuntu11.1 grub2-common from 2.02~beta2-36ubuntu11 to 2.02~beta2-36ubuntu11.1 grub-efi-amd64-bin from 2.02~beta2-36ubuntu11 to 2.02~beta2-36ubuntu11.1 grub-common from 2.02~beta2-36ubuntu11 to 2.02~beta2-36ubuntu11.1 Additionally when this update is performed shim-signed is uninstalled (dependency not met). After manual changing package version requirements in shim-signed package to met shim package dependency and install modified shim-signed package system still not boot in secureboot. That means the problem is in one of new version of these packages: shim grub-efi-amd64 grub-efi-amd64-signed grub2-common grub-efi-amd64-bin grub-common When I reverted changes to: shim 0.9+1465500757.14a5905.is.0.8-0ubuntu3 grub-efi-amd64 2.02~beta2-36ubuntu11 grub-efi-amd64-signed 1.74+2.02~beta2-36ubuntu11 grub2-common 2.02~beta2-36ubuntu11 grub-efi-amd64-bin 2.02~beta2-36ubuntu11 grub-common 2.02~beta2-36ubuntu11 shim-signed 1.21.3+0.9+1465500757.14a5905.is.0.8-0ubuntu3 everything back to normal, system boot with secureboot enabled.
