Problem: 
a stop job is running for ifup 
a stop job is running for NetworkManager
Why: 
Debian Jessie and jessie-backports systemd versions 2.15 and 2.30 respectively have a small bug that stalls shutdown.
Tentative Solution: (i.e. unofficial; your mileage may vary) 
edit /etc/systemd/system/network-online.target.wants/networking.service,  replacing
ExecStop=/sbin/ifdown -a --read-environmentwith
ExecStop=/sbin/ifdown -a --read-environment --force --ignore-errorsand also
TimeoutStopSec=5minwith
TimeoutStopSec=5s~~~

delete "no-auto-down eth0" in /etc/network/interfaces
