Additional information you deem important (e.g. issue happens only occasionally):

One of a workaround for it is to upgrade the packages:
#10732
It is upgrade the package libdpkg-perl to 1.19.8 to fix it, see files/build/versions/dockers/docker-platform-monitor/versions-deb-buster

Another option, it is to add the package dpkg-dev=1.19.7 to files/build/versions/dockers/docker-platform-monitor/versions-deb-buster. We should support it automatically.

Analysis

The issue is caused by not freezing all the versions in the docker image. The package pkg-dev is not in the version file, but there is an intermediate package upgrade for the package. We only keep the diff version in the version file, and generate the version preference file in /etc/apt/preference.d.

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 dpkg-dev : Depends: libdpkg-perl (= 1.19.8) but 1.19.7 is to be installed
E: Unable to correct problems, you have held broken packages.

It tried to install the dpkg-dev=1.19.8 as below. Add the dpkg-dev=1.19.7 in the preference file, will fix it.

$ grep libdpkg-perl files/build/versions/dockers/docker-platform-monitor/ -r
files/build/versions/dockers/docker-platform-monitor/versions-deb-buster:libdpkg-perl==1.19.7

Options solutions:

1. Generate all the version in the version file files/build/versions/dockers/docker-platform-monitor/versions-deb-buster
2. Generate the preference file based on the base image versions + the diff versions (override the base image versions if the same package).

For the version preference setting, both of the solutions are the same, the option 2 keeps the version file small, less redundant version info.
