    Problem solved. I switched to Network-Manager in Netplan.

    Since 17.10 Ubuntu Server, the Netplan utility has been used to manage the network configuration.

    So, create this file:

    /etc/netplan/00-enable-network-manager.yaml

    And put this content and save:

    network:
  version: 2
  renderer: NetworkManager

    Then disable the default configuration:

    cd /etc/netplan
sudo mv 00-installer-config.yaml 00-installer-config.yaml.bak

    It may need a restart of the NetworkManager service or maybe a reboot.

    IMPORTANT: before doing so, be sure that you have physical access to the server, since it may be not reachable after this change.
