Fixed ethernet connection after installing Ubuntu Server 18.04
Reading Time: < 1 minute
For some reason, Ubuntu server 18.04 does not start with a valid ethernet connection on my newly acquired, an oldie but goodie, Dell R710 server. After some searching around this solution at tecmint that works for me.
sudo netplan generate
sudo vim /etc/netplan/01-netcfg.yaml
ifconfig -a # find the ethernet name, mine is eno1
# this will auto config using DHCP
network:
version: 2
renderer: networkd
ethernets:
eno1:
dhcp4: yes
dhcp6: yes
sudo netplan apply
ifconfig -a # should now show IP on eno1
