** Description changed:
[Impact]
* /etc/kernel/{postinst.d,postrm.d}/zz-update-grub missing on arm64
- with grub-efi-arm64-signed installed, without grub-efi-arm64.
+ with grub-efi-arm64 (a dependency of grub-efi-arm64-signed) installed
* /etc/kernel/{postinst.d,postrm.d}/zz-update-grub missing on amd64
- with grub-efi-amd64-signed installed without grub-pc or grub-efi-amd64.
+ with grub-efi-amd64 (an ORed dependency of grub-efi-amd64-signed)
+ installed.
* This results in newly installed kernels not getting added to grub.cfg
and thus upon reboot one does not boot into the new kernel.
- * In later series these scripts moved to grub2-common. Maybe we should
- move these to grub2-common in bionic and earlier too, for compatibility
- with onegrub. Or alternatively grub2-signed should ship these in grub-
- efi-{amd64,arm64}-signed packages too.
+ * In later series these scripts moved to grub2-common, which is why
+ they are absent in the backported grub-efi-* packages. They should be
+ restored to these packages in the backport.
[Test Plan]
* Install new grubs

grub-efi-arm64-signed is installed.

+ * If testing on amd64 ensure that grub-efi-amd64 and grub-pc are not
installed; and grub-efi-amd64-signed is installed.
* Install a new kernel that was not installed before
* Observe that grub.cfg is regenerated and new kernel is present
* Remove an old kernel
* Observe that grub.cfg is regenerated and new kernel is removed from
grub.cfg
[Where problems could occur]
* These are conffiles. Although nobody should modify them, care should
be taken when moving conffiles around.
