Failed to start Raise network interfaces.

So, I tried to change my MTU today and was greeted with the following error when I went to apply the changes.

I logged into ssh and executed systemctl status networking.service and received the following:

I then executed journalctl -xe and received a huge wall of text. Will paste if it'll help resolve this.

The above line is the problem, have a look here from post 7 but whatever you do it must be done directly on OMV not via ssh

Here's what I get when I run /etc/init.d/networking restart

Restarting networking (via systemctl): networking.serviceJob for networking.service failed because the control process exited with error code.
See "systemctl status networking.service" and "journalctl -xe" for details.
failed!

Yet, everything will seem to work fine again. I just can't change any networking options via the OMV interface.

As in the MTU value? Mine isn't set and I'm using a static IP, it's something I have never changed nor set up.

Correct. Nothing can be changed without that error coming up.

The default value is 1500, I did do forum search for MTU and TBH there is not a lot.

If I try to change anything, my DNS, my IP, my WOL enabled/disabled, i get this error. I literally can not change anything network related.

I wonder! if clearing your browser cache and/or omv-firstaid option 10 to clear the web panel cache would help.

Already tried the browser cache, but it's definitely an issue with debian. Apparently it is kind of common according to google, something to do with the predictable adapter names, but none of the fixes that I've tried have worked.

Networking seems fine, if I need to change anything it seems I have to manually update my /etc/network/interfaces file with nano and then reboot the machine since trying to restart networking services results in this error. When I reboot the boot journal also says same thing about not being able to start networking due to not being able to raise network interface.
