Failed to start raise network interface on Ubuntu 16.04

Question

All of sudden I am getting failed to start raise network interface error messages in Ubuntu. Any feedback will be great help.

I tried the following steps but still the problem exists:

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!

root@storage:~# ping 192.168.0.227

Solution

Maybe a bit late, but I had the same issue, but then with ip6tables that gave an error :

$ 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.

My /etc/network/if-pre-up.d/ip6tables looked like this:

ip6tables-restore < /etc/ip6tables.conf

I solved the issue by adding a shebang on top of the script to make it look like this:

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

Now my interface is willing to come up. I hope this solution might help you (and others that stumble across this post).

Can you check the service "networking" not "network", I think thats the correct name. Also, is this a server or a desktop ?

[jeroen]

If you are using network-manager, then the correct syntax would be: (sudo) systemctl stop NetworkManager.service you can also replace stop with restart. The capitol N and M inthe command are mandatory

[jeroen]

Furthermore you are able to check the status of your network interface with (sudo) ip link somtimes it helps to bring the interface down and up manually: (sudo) set ip link eth0 down and afterwards (sudo) set ip link eth0 up eth0 is an example use the interfacename you got with (sudo) ip link.

If you want to use HTML to mark up terminal output, you can surround it with <pre> and </pre> to make it look good.
