systemd is an innocent party here; the operation was completed by dpkg and
then the communication back and forth between apt and dpkg goes a little awry
due to recent changes.

The messages are harmless and don't occur in the default configuration (always
purging is likely required) or when following the two-step upgrade procedure
as normally recommended (upgrade followed by dist-upgrade).
It's likely that we want to document them in the release notes for buster if
there is no way of preventing them from every appearing; apt developers, can
you please clone this bug to release-notes if that is indeed the case?
