Как полностью сбросить параметры сети на 18,04?

Я обновил до Ubuntu 18.04, и внезапно у меня нет Интернета на командной строке, соединенной проводом, ни беспроводная связь, некоторые домены, кажется, не решают, хотя ping 8.8.8.8 действительно работает, но service networking status производит ошибку. Я видел много тонких настроек здесь на askubuntu относительно проблемы, с ifconfig или /etc/network/interface но ни один полностью не работает. sudo service network-manager restart не работает также.

Моя сеть является в основном путаницей. Существует ли способ полностью сбросить параметры сети к функциональному? Как возможно, что Ubuntu выпускает основной дистрибутив с такой ошибкой, так как это - горячая тема вокруг?

Ubuntu 18.04 больше не использует ifupdown (/etc/network/interfaces). Это - то, куда Вы идете неправильно

, Они переключились на netplan, огромную боль. Посмотрите больше информации здесь

Я, оказывается, решаю этот выпуск фабрикой, сбрасывающей определения маршрутизатора.
