Public bug reported:
Got this while running a regular upgrade today (already on Ubuntu
18.04):
Setting up grub-efi-amd64 (2.02-2ubuntu8.3) ...
warning: file-aligned section .text extends beyond end of file
warning: checksum areas are greater than image size. Invalid section table?
E: Your kernels are unsigned. This system will fail to boot in a secure boot
environment.

This appears to be triggered because I have installed (and am running)
linux-modules-4.18.3-041803-generic from the Ubuntu mainline kernels PPA. The
kernel works just fine with secureboot enabled. It is required due to the
extreme instability of the stock kernel on my XPS 13.
This appears to be related to #1786491. But why prevent the installation if it
works just fine?
I also DO have the regular signed images (linux-generic and linux-oem)
installed, so just because I have one unsigned kernel installed, it is borking
up my whole system. In the middle of a stable release cycle, which seems
insane to me.
I understand wanting to prevent someone from winding up with an
unbootable system, but this patch is going far beyond that.
