I am getting a failed to start networking error while booting. I am also no able to change any networking settings in the gui or with firstaid. The weird thing is, in the gui it is showing a network interface that does not exist, or that is not in my interfaces file. Here are my errors.
root@mymediavault:/etc/openmediavault# systemctl status networking
● networking.service - Raise network interfaces

Here is my interfaces file
# Include additional interface stanzas.
source-directory interfaces.d
# The loopback network interface
auto lo
iface lo inet loopback
# enp3s0 network interface
auto enp3s0
allow-hotplug enp3s0
iface enp3s0 inet static
address 192.168.1.160
gateway 192.168.1.1
netmask 255.255.255.0
dns-nameservers 192.168.1.1 8.8.8.8
iface enp3s0 inet6 manual
pre-down ip -6 addr flush dev $IFACE
However here is what the gui shows
Network Gui
What is actually working is what the interface file shows. When I try to change it from within the gui , i get an error about the networking service and to see the status with systemctl status networking as shown above.
Any idea whats going on?
