Ubuntu 20.04 Network setup with NetPlan and NetworkManager

ubuntu_nic_netplan.md

Whut?!

Ubuntu 18.10 and onwards use netplan for the configuration of network interfaces. although im fine with it, it seems Cockpit and some other software dont like it as much.

Solution

Let Netplan configure the interface and hand-off further managent to NetworkManager.

notice: NetworkManager is not a X Application, although the name might sound like one.

Action!

If you have been toying arround with it, set back to defaults

sudo systemctl enable network-manager.service
sudo systemctl start network-manager.service

Now edit /etc/netplan/00-network.yaml like this

network:
  renderer: NetworkManager
  ethernets:
    eno1:
      dhcp4: false
      addresses:
        - 10.13.37.2/24
      gateway4: 10.13.37.1
      nameservers:
        search: [sacredheart.lan]
        addresses: [10.13.37.3]
  version: 2
