I'm trying to get my new Ubuntu Server install connected to the internet, but Im running into an issue. I cant even ping the router that the server is directly plugged into via Ethernet. I've tried looking at a number of forums and setting the OS to use DHCP, setting static IPs, etc. And now I am here. Hoping that someone can point out where my problem lies.
This is a fresh install of Ubuntu Server version 18.04.3
Command outputs (note, typing this on a phone):
$ ifconfig enp3s0: flags=4163<UP, BROADCAST, RUNNING, MULTICAST> mtu 1500 inet6 <IPv6address1> prefix 64 scopeid 0x0 inet6 <IPv6address2> prefix 64 scopeid 0x20 ether <macHere> ...
point is, ethernet iface is up, but no IPv4 listed. Only other interface is
$ cat /etc/network/interfaces auto lo iface lo inet loopback auto enp3s0 iface enp3s0 inet static #Ive tried dhcp here in place of static, without the following lines address 192.168.1.101 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1
Router gateway is 192.168.1.1, I've double checked
$ cat /etc/hosts 127.0.0.1 localhost 127.0.1.1 <hostname> ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters
/etc/resolv.conf is managed by
systemd-resolved so I would prefer not to manually edit this
$ cat /etc/resolv.conf nameserver 127.0.0.53 #??? Don't understand why this is options edns0
$ systemd-resolve --status ... Link 2 (enp3s0) Current Scopes: none LLMNR setting: yes MulticastDNS setting: no DNSSEC setting: no DNSSEC supported: no
ip route show and
ip route list do not print anything to stdout
Please let me know what I can do to fix this issue. I can edit this post with more output if needed
EDIT: While the potential duplicate question is similar, it does not provide a solution on how to connect to the internet with the tools available on the system (aka netplan). That question is asking how to switch back to
etc/network/interfaces, and the currently accepted answer is to
apt install ifupdown (which is a brilliant idea considering networking is unavailable).
