This server is running as a VM on Unraid and has been working fine until a recent power outage caused an unexpected shutdown.

All other VMs connect to the internet fine.

Since it is headless, I am only able to connect to it via Unraids built-in VNC viewer and am not able to ssh into it since it is not connected to the network.

ifconfig returns (sorry can't copy code because of vnc):
Screenshot

ping 8.8.4.4 returns:

connect: Network is unreachable

Looking at the interfaces file (/etc/network/interfaces) shows:
Screenshot 2

and due to the lack of internet, I am unable to install or reinstall packages...

UPDATE:

I have since found a post on StackOverflow that helped me get the internet running. But it appears to be temporary (until next restart).

The command that made it work is:

 sudo dhclient -v -4

https://askubuntu.com/a/1047291/

How can I make it permanent?

Any help would be greatly appreciated

Thank you!
