How to restore networking after droplet rebuilt from an image?
I took a snapshot of my Ubuntu after which I destroyed it. Now I'm trying to restore it and I'm having problems with networking. I only have the loopback lo at 127.0.0.1.
In the previous droplet I had eth0 defined in /etc/network/interfaces.d/00-default.cfg. Now I got a new public IP and most likely a new subnet IP. Before it was 18.104.22.168. Now I don't know what it is nor how to check it.
When I do:
systemctl restart networking
it fails, and journalctl -xe contains a line with "Failed to start Raise network interfaces."
How can I recover and get the net working?
