Public bug reported:

On most systems I administer, both debsums and unattended-upgrades are
installed and run from cron daily.

unattended-upgrades has been configured to wait for a random amount of
time before doing its thing, and this every now and then causes it to
perform an upgrade at the time debsums is running.

During such an upgrade (especially of large packages like kernel
headers), debsums can find a mismatch between the files on disk and the
checksums, but these are false positives.

I guess this can be fixed by adding an option to debsums to let it
(read-)lock the dpkg admin dir before doing its job, so it can be
prevented from running concurrently with software altering package
state.

The bug has been observed on 16.04 systems with all upgrades applied,
but looking at the debsums changelogs I see no reason to believe this
has been fixed.
