That would depend on which version of Debian, and how far down the
"everything will be absorbed into systemd" path they have gone.

If it has the same problems as the beta releases of Ubuntu 18.04,
where systemd has effectively taken over networking (via networkd and
the netplan.io package), then you need to do a bit of work to continue
using the /etc/network/interfaces and the ifup/ifdown scripts:

1) Install the ifupdown package (or ifupdown2).

2) Enable the "legacy" networking service in systemd:
    sudo systemctl enable networking
    sudo systemctl start networking
