ping google.com: unknown host (can still ping IPs)
I previously had connectivity on this server, but now I can't ping hostnames. I can ping IPs. I'm no Linux expert so I don't know how much of this is relevant, but I've noticed the following:
a) /etc/resolv.conf is empty.
b) The networking service has a "stop/waiting" status, but network-manager is running.
c) I noticed the problem since creating a Snapshot. This involved shutting down the server. Perhaps the restart caused an issue?
Any help is much appreciated!
