Hi List,

Noting here a solution from the debian-user mailing list.

I'm aware there's a team working for init system flexibility
on Debian and send my kudos and beer vouchers to them :-)

A warning about all of these solutions: They will remove the package, network-manager.
Sometimes this may rewrite the “/etc/network/interfaces” file. You can loose network connectivity after a reboot as a result.
Be prepared to login to the console and fix that up manually if it happens.

Another work-around is to, before doing any apt stuff at all, put a suitable fragment into the “/etc/network/interfaces.d/“ directory that configures at least one of your network interfaces the way you want it. As an example, on my test system I have:

> $ cat /etc/network/interfaces.d/enp0s3
> auto enp0s3
> iface enp0s3 inet dhcp

Hope it helps!
Rick
