J'ai mis à niveau vers Ubuntu 18.04 et tout à coup, je n'ai pas Internet en ligne de commande, filaire ou sans fil, certains domaines semblent ne pas résoudre, bien que ping 8.8.8.8
fonctionne, mais service networking status
génère une erreur. J'ai vu de nombreux ajustements ici sur askubuntu concernant le problème, avec ifconfig
ou /etc/network/interface
mais aucun ne fonctionne pleinement. Sudo service network-manager restart
ne fonctionne pas non plus.
Mon réseau est essentiellement un gâchis. Existe-t-il un moyen de réinitialiser complètement les paramètres réseau en fonctionnels? Comment est-il possible qu'Ubuntu publie une distribution principale avec un tel bug, car c'est un sujet brûlant?

Ubuntu 18.04 n'utilise plus ifupdown (/ etc/network/interfaces). C'est là que vous vous trompez
Ils sont passés à netplan, une énorme douleur. Voir plus d'informations ici
Il se trouve que je résout ce problème en réinitialisant en usine les définitions du routeur.
