Unable to make changes to network interface

  • Dear all,


    I want to make some tests and am trying to activate IPv6 on my main network interface. However, if I make any changes (not only when I try to activate IPv6) I get an error message when I try to save the changes.


    Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; systemctl start 'networking' 2>&1' with exit code '1': Job for networking.service failed because the control process exited with error code. See "systemctl status networking.service" and "journalctl -xe" for details.


    I checked the output of the given commands:


    root@ZBOX:~# systemctl status networking.service

    ● networking.service - Raise network interfaces

    Loaded: loaded (/lib/systemd/system/networking.service; enabled; vendor preset: enabled)

    root@ZBOX:~#


    If necessary I can post the output of


    root@ZBOX:~# journalctl -xe


    but for the moment I don't have enough understanding to filter what of the enormous output might be relevant.


    I already tried to reconfigure the network interface with omv-firstaid but at the end I get the same error message as initially posted.



    I would be very thankful for any ideas how to fix this problem.
