Falha ao iniciar o aumento da interface de rede no Ubuntu 16.04

Question

De repente estou recebendo failed to start raise network interface mensagens de erro no Ubuntu. Qualquer feedback será de grande ajuda.

Eu tentei as etapas a seguir, mas o problema continua:

root@storage:~# systemctl stop network
Failed to stop network.service: Unit network.service not loaded.

root@storage:~# systemctl disable network
Failed to execute operation: No such file or directory

root@storage:~# /etc/init.d/networking restart
[....] Restarting networking (via systemctl): networking.serviceJob for networking.service failed because the control process exited with error code. See "systemctl status networking.service" and "journalctl -xe" for details.
 failed!

Answer 1

Talvez um pouco atrasado, mas tive o mesmo problema, mas com o ip6tables que deu um erro:

$ sudo ifup ens160
run-parts: failed to exec /etc/network/if-pre-up.d/ip6tables: Exec format error
run-parts: /etc/network/if-pre-up.d/ip6tables exited with return code 1
Failed to bring up ens160.

Meu /etc/network/if-pre-up.d/ip6tables ficou assim:

ip6tables-restore < /etc/ip6tables.conf

Eu resolvi o problema adicionando um shebang no topo do script para torná-lo assim:

#!/bin/sh
ip6tables-restore < /etc/ip6tables.conf

Agora minha interface está disposta a aparecer. Espero que esta solução possa ajudá-lo (e outros que tropeçam neste post).

No meu caso, isso é causado por mais de um gateway em um sistema. Basta remover o gateway em uma das suas interfaces e tentar reiniciar o serviço de rede. Eu trabalho em mim
