NetPlan, NetworkManager, GUI - networking

This is just for people wanting to use NetPlan and NetworkManager, eg. if they have lots of VPNs etc.

  • you first need networking to work in any way (see guides) so you can use apt to install new packages
  • once you have working connection run these commands in WSL:
sudo su
  <password>
apt install network-manager
apt install network-manager-gnome
  • with packages installed we need to reconfigure networking, if you've used systemd guide that means deleting some files, and creating new ones
  • we create one empty files to let NetworkManager know it will manage connections
  • we remove old .network config that contains networkd configuration
  • we remove old resolv.conf that was manually created to manage DNS (nameservers)
  • we create link to new resolved stub allowing it to manage DNS behind the scenes
  • we create actual NetPlan config (DHCP, later we can change this in GUI)
touch /etc/NetworkManager/conf.d/10-globally-managed-devices.conf
rm /lib/systemd/network/wsl_external.network
rm /etc/resolv.conf
ln -s /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf
nano /etc/netplan/01-netcfg.yaml
  • .yaml file contents, the following is YAML and it is very sensitive to spacing, use copy paste
network:
  renderer: NetworkManager
  ethernets:
    eth0:
      dhcp4: yes
  version: 2
  • tell NetworkManager it may manage connections, edit file, change managed=false to managed=true in this file
nano /etc/NetworkManager/NetworkManager.conf
  • apply all settings and enable all services, then show eth0 settings
systemctl enable NetworkManager
systemctl restart NetworkManager
netplan apply
ip a
nmcli device show eth0
  • nmcli on my WSL instance showed this (DHCP assigned)

  • you can now setup static IP with GUI tools installed earlier
nm-connection-editor &
  • I've used GUI to delete manually created DHCP config, created new config, used eth0, assigned static IP, static DNS, etc.
  • Save changes in GUI, and then close GUI Network Manager, it should automatically apply new settings to your network interface
  • now check network status, it should show new settings applied
  • ip a output

  • notice that IP and DNS show new values
  • restarting should keep everything running as is automatically
