    NMCLI connection problem

    Good afternoon.

    I have need to have an Ubuntu system (20.04) to VPN into a client site, and copy files to a Windows share on that site, then disconnect, but I have a problem...
    I know the actual VPN links works OK at the destination as I have it currently running in a Windows-to-Windows environment, but the source/originating box has been changed to Ubuntu.

    I have followed several guides and created a VPN entry with NMCLI (which went OK), however, when I run it:
    nmcli c up vpnname
    The error received is:
    Error: Connection activation failed: Could not find source connection.

    If I read it right, it appears that the eth0 interface is not managed by nmcli (as shown by "nmcli device status"), so I need to change it so the response is "full" not "none".

    I cannot find much information on how to troubleshoot this error. Is somebody able to give me a hint please?

    I know there is no short answer to this whole topic as I have seen it in many similar posts, but if I can have eth0 managed by Network Manager I'll be a little further along.

    Any pointers are appreciated.
