I just finished installing the new Ubuntu 19.04 Server on my downstairs server, but it doesn't appear to have an internet connection despite being wired to the router using a cat-6 cable.
All pings fail, including
ping 18.104.22.168 with the same error message. I've tried using
ifconfig to set the state to
up, but this didn't help.
ip a reveals that the server doesn't seem to have an IP address.
