🔧 Proven Troubleshooting Steps
Enabling systemd-networkd via Systemd
- Step 1: To enable systemd-networkd, first ensure that it is installed on your system. You can do this by running the command `sudo apt-get install systemd-networkd` (for Ubuntu-based systems) or `sudo yum install networkmanager` (for RPM-based systems).
- Step 2: Next, restart the systemd service to activate the changes: `sudo systemctl restart systemd-networkd`. This should enable the display of interfaces using the `networkctl` command.
- Step 3: Verify that systemd-networkd is running by checking its status: `systemctl status systemd-networkd`. If it's not running, you may need to manually start it: `sudo systemctl start systemd-networkd`.
Enabling systemd-networkd via Netplan
- Step 1: If the issue persists, try enabling systemd-networkd using netplan. First, ensure that your network configuration is set up correctly in the `netplan` file.
- Step 2: Edit the `netplan` file to include the `networkd` section, which enables systemd-networkd: `sudo nano /etc/netplan/00-netcfg.yaml`. Add the following lines to the file: `network: ethernets: ens33: match: macaddress:
network: ethernets: enp4s5: match: macaddress: ` - Step 3: Save and close the file, then apply the changes: `sudo netplan apply`.
💡 Conclusion
