[Bug 1814384] Re: update-initramfs: failed for with 1.

[martin suc]

Because it happened even by upgrade from 18.04 LTS to 19.04 again when
mnually installed kernel version 5 ... temporary solved by putting
following code in /etc/kernel/postinst.d/kdump-tools

...
if [ -z "${version}" ]; then
	echo >&2 "W: kdump-tools: ${DPKG_MAINTSCRIPT_PACKAGE:-kdump-tools package} did not pass a version number"
	exit 2
fi


echo "--- new temporary code taken from package kdump-tools"
if ! linux-version list | grep "${version}" > /dev/null ; then
	exit 0
fi
echo "------"

# exit if kernel does not need an initramfs
if [ "$INITRD" = 'No' ]; then
	exit 0
fi
...
