Bug#913454: dpkg: warning: found unknown packages; this might mean the available database...

Control: reassign -1 apt 1.7.0
Control: severity -1 minor

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?

(based on comments from DonKult on IRC; insightful comments are his and errors 
are mine)

Cheers
Stuart
