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.
