Comment 12 for bug 2007827

I've been generating kernel images with this script from the raspberry pi foundation kernels for some time:

https://gist.github.com/satmandu/a507c59d84737f6d29ff353395819d51

flash-kernel gives me this error now in lunar:

Using DTB: bcm2711-rpi-4-b.dtb

Installing new bcm2711-rpi-4-b.dtb.
dpkg-query: no packages found matching

I've had to modify /var/lib/dpkg/info/flash-kernel.postinst to have "exit 0" at the end, and I've also modified the beginning to replace "set -e" with "set -x" to get some more info on what's happening.

Trying to install the latest generated image, I get this error:

(without the exit 0, flash-kernel always quits with an error, leaving the install of the kernel broken.)

I can't tell if the flash-kernel breakage is connected to this change or not... but I can't understand why there is a dpkg-query error here.

I do see this:
