APT had planned for dpkg to do more than it reported back

When running the concerto-full Debian install, users get the following warning upon successful completion:

W: APT had planned for dpkg to do more than it reported back (0 vs 4).
Affected packages: concerto-full:amd64

This makes it sound like a non-issue. I have no idea how to troubleshoot and resolve this.
