Соединение Ethernet Kubuntu 16.10, не работающее после обновления версии

После обновления от Kubuntu 16.04 LTS до 16,10 не работает проводное соединение. Проводное соединение отображено в Администраторе сети, но не возможно нажать относительную кнопку "Connect". Соединение Wi-Fi работает.

Странная вещь состоит в том, что с помощью Kubuntu 16.10 живой USB на том же ПК соединение Ethernet сразу распознано и работа.

Это некоторые результаты:

После некоторых предложений я загрузил драйвер r8168 вместо r8169 без успеха. ПК является NUC DN2820FYK.

Заранее спасибо за Вашу справку.

Это - результат предложенной команды:
