Upgrading debian packages across releases is not supported.
You either upgrade jessie->stretch->buster->.. (if I remember
the codenames right), or you install a new server and migrate,
as Rowland suggested.  Or you remove old samba completely
(purge) and install new after upgrading the server.

While samba itself can be upgraded right to current version,
but the packaging is not prepared for this. In particular,
"samba4" startup script has been there when debian moved from samba3 to samba4. It's been renamed to "samba"
a few releases ago, and that rename has been removed in subsequent
releases. So if you upgrade from debian samba 4.1 package to
debian samba 4.16 package, you'll have two startup scripts
which will conflict with each other.

usr/local/ really?

This is not a debian package.
