Failed to start raise network interfaces ошибка

I just upgraded a virtual 14.04 server machine to 16.04. After rebooting the VM I see the following error:

[FAILED] Failed to start Raise network interfaces.
 See 'systemctl status networking.service' for details

After login I can run the mentioned command and get the following output (image as I’m not able to connect):

enter image description here

The configuration in /etc/network/interfaces looks fine — featuring the manually configured eth0 (not using dhcp here)

What makes me wondering is that ifconfig -a lists

  • ens160
  • lo

Where I would expect

  • eth0
  • lo

Trying to up the eth0 device via

sudo ifup -v eth0 

outputs:

...
Cannot find device "eth0"
Failed to bring up eth0.

The virtual wired network device itself is still configured in the VM itself as it was before.

ip link shows as well lo and ens160 — where ens160 has the mac address configured in vmware for the single configured virtual network device.

UPDATE

I am able to solve the issue if i change all references of eth0 in /etc/network/interfaces to ens160.

BUT — this feels wrong for me for several reasons:

  1. I would like to understand this problem
  2. I would like to stick to eth0 instead of ens160

So please can someone explain this change, which didn’t happen to several other 14.04 machines on the same server which I also upgraded to 16.04.

On a fresh installation of Debian 9 Stretch on a desktop PC when booting the

...
Failed to start Raise network interfaces
...

error occurres. The (cable) LAN-connection works but the (USB) WiFi is not working properly (detecting the WiFi networks but failing to connect). Previously on the same harware Debian 8 Jessie was installed working fine without any errors.

Seems the issues are connected to the recent predictable network interface names changes. Found users A, B, C, D, and E had similar symptoms. However, they had upgraded Ubuntu systems (without a clean install). Aditionally the proposed solutions are suggesting disabling the assignment of fixed/predictable/unique names. I would prefer to keep the new naming scheme/standard, eventually to find and eliminate the reason why(?) it is not working properly.

Found also users F, and G with the same problem — without solution.

Would be very thankful for any hint. Also, I’m happy to answer your questions if you need more in depth details.

Further you find some detailed system output.

Имена интерфейсов надо брать из ip l

команды разные, но имена отображаются одни и теже
тоесть ошибки в имени нет


Пользователь добавил сообщение 01 Сентября 2016, 20:22:21:


Короче дошел до следующего:
если руками не трогать файл /etc/network/interfaces а запускать локальный интерфейс командой sudo ifconfig eth0 up 192.168.0.1 netmask 255.255.255.0   —  то все работет и никаких ошибок не наблюдается !!!

происходит это так:
перегружаю сервак

после перезагрузки выполняю ifconfig: вижу только интерфейс петля

подключаю РРРоЕ, сразу появляются ррр0, eth1 (это наружные интерфесы) и eth0 (локальный интфейс) но без ip-адреса
на этом этапе сервак можно рестартовать сколько душе угодно, при этом интерфесы сохраняются, интернет на серваке есть, нетворкинг работает без ошибок!

выполняю sudo ifconfig eth0 up 192.168.0.1 netmask 255.255.255.0 — появляется ip-адрес на eth0

делаю рестарт службы DHCP и сразу же в локальную сеть полетели адреса  и следом за ними интернет, при этом все работает без ошибок

проблема исчезает, все работает, думаю написать скрипт, который будет поднимать eth0 после перезагрузки машины и можно сказать что проблема «типа решена»

но так и не могу понять, почему если я прописываю настройки для eth0 в /etc/network/interfaces   —   сразу получаю Failed to start Raise network interfaces

I am setting a Ubuntu’s VM (16.04.1 LTS) and I get an error when I try to connect from WinSCP in my windows to the VMs. The error is: developmentHost does not exist.

The network/interfaces file is this one:

enter image description here

If I execute a ifconfig command I get this info:

enter image description here

On the other side, the Virtualbox configuration for both network adapters are:

Adapter 1

In the above picture I included the port redirection, because I want to connect with the VM withou editing the windows hosts file.

Adapter 2

Furthermore I get this error about interfaces when I reboot.

I don’t know how to fix the failure but i can show you a shortcut to deal with this problem temporarily…

1-use this command to find out which interfaces are available in your system.
# ip link
example: lo , enp0s8

2-add following lines in /etc/network/interfaces

auto enp0s8
iface enp0s8 inet dhcp

3-restart your VM.
and it’s done.

In Ubuntu 16.04 there perhaps is no ethX interface anymore. This version now comes with the so called Predictable Network Interface Names, where the name of the interfaces can be determined by: which tries to find fixed slot topology information in certain firmware interfaces and uses them to assign fixed names to interfaces which incorporate their physical location on the mainboard. (refer to: freedesktop.org). Hence you have to find out the correct interface names by using the command ip a which prints something like:

1: lo: ...
2: ensXX: ...
n: ...

before you can configure your /etc/network/interfaces

You mentioned something about a VM, if the hardware address changes then you might have the same issue as if you changed physical hardware.

Get current identifier for the network card:

root@mybox:/home/root# ip -a

1: …

2: enp0df: …. (Your identifier will be different)

Update this information in:
/etc/network/interfaces

# The primary network interface

auto enp0df

iface enp0df inet dhcp

Restart network services:

/etc/init.d/networking restart

i think you should change network advanced option.
if you set option modo promisco to Permitir todo(permit all), it will work fine.

Edit: I found the solution, but I don’t know why it worked if anyone can explain why this solution worked, I would be grateful. I’m interested in learning. I’m going to be reading this forum post to figure out why it worked.

from https://unix.stackexchange.com/a/448291

Code: Select all

    Just putting a #

    in front of source /etc/network/interfaces.d/* in the /etc/network/interfaces file, so it doesn't reference the /interfaces.d/setup file solved it for me. Everything working fine. The solution is kinda logical.

—these commands are from my computer—

This is the output of cat /etc/network/interfaces.d/setup

Code: Select all

auto lo
iface lo inet loopback
auto etho0
iface eth0 inet dhcp

This is the output of cat /etc/network/interfaces

Code: Select all

#this file describes the network interfaces available on your system
# and how to activate the,/ for more information, see interfaces(5)
#sources /etc/network/interfaces.d/*

#the loopback network interface
auto lo
iface lo inter loopback

——original post——-

I get this error while booting

Code: Select all

[Failed] failed to start Raise network interfaces.
see 'systemctl status networking.services' for details. 

When I run the above command (systemctl status networking.services) I get

Code: Select all

networking.service - Raise network interfaces
Loaded: loaded (/lib/systemd/system/networking.service; enabled; vendor preset; enabled)

Main PID: 790(code=exited, status =1/FAILURE)

This is a fresh install of debian stable on a desktop pc. My guess is the networking module is failing to load.
My internet works with the Ethernet cable, If anyone knows how to fix this error, and could help me, it would be greatly appreacited, Thank you.

I don’t know if this is helpful, but I did find someone with a similar error https://unix.stackexchange.com/question … interfaces

/etc/network/interfaces.d/setup is bogus. Just remove it instead of messing with defaults in /etc/network/interfaces.
I have seen several reports about this file but don’t know yet what creates it. I have never seen it on any of my Debian installations.
Could you tell us how exactly you installed Debian ?
Which version and architecture did you install ?
What ISO image did you use ?
Did you use the classic Debian installer (from boot) or the Calamares installer (from a live session) ?
What options did you select in «select and install software» (tasksel) ? Which desktop environment did you install ?

This is a perfectly valid file, if the OP created it…!
Do remove the duplicate defaults, only mention additions.
No package I know of creates it. If it is chosen not to have any network manager type packages installed then this is the proper place for network configuration created by the user.

From interfaces(5)
» By default, on a freshly installed Debian system, the interfaces file includes a line to source files in the /etc/network/interfaces.d directory.»

No it is not valid as this system has no «eth0» interface, and the OP did not create it.
As I wrote, this file happens to be present with these exact name and contents on some systems after installation. I strongly doubt that multiple unrelated users had the same stupid idea and created the exact same file.

There are errors there… Is there an «etho0», no. Is there an «eth0» maybe!
Check the actual interface name and edit correctly

Code: Select all

allow-hotplug eth0

crossposted edit, yes p.H. I saw that and didn’t grab it, not on screen, argh, went back to quote..

Sorry for the late response.

Could you tell us how exactly you installed Debian ?

debian live 10.7.0 xfce live image, I used graphical install. I checked the hash and gpg signature of the iso. It’s an older image, I flashed it around february or march.

Which version and architecture did you install ?

debian stable. The architecture is amd64, a desktop pc.

What options did you select in «select and install software» (tasksel) ?

It didn’t let me choose, this was from a xfce live debian image, so it installed xfce automatically.

I did not create /etc/network/interfaces.d/setup

I ran the command dpkg -S /etc/network/interfaces.d/setup and got

Code: Select all

dpkg-query: no path found matching pattern /etc/network/interfaces.d/setup

I guess that «etho0» is a typo in the post.

It is, I’m sorry for the typo I made, the output of cat /etc/network/interfaces.d/setup is

Code: Select all

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

Did you use the classic Debian installer (from boot) or the Calamares installer (from a live session) ?

classic graphical installer from boot. Although it’s from a live image of debian.

I also installed firmware-linux-nonfree, I don’t know if that package has anything to do with this.

I have a separate install of debian stable on this machine, from 2 years ago on a separate drive. I checked and the file /etc/network/interfaces.d/setup doesn’t exist. The installer I used for that old debian install is a debian 10.0.0 iso.This file might be something created from the debian 10.7.0 xfce live installer.

What fix would you recommend? should I delete /etc/network/interfaces.d/setup

or

Check the actual interface name and edit correctly

allow-hotplug eth0
iface eth0 inet dhcp

the file could be setup.conf or eth0.conf, it does need the .conf part.
Substitute eth0 with it’s actual name in both lines.
To check the name, renaming, ask as root, or sudo

Code: Select all

#  dmesg | grep eth
[    3.718939] igb 0000:06:00.0: added PHC on eth0
[    3.718943] igb 0000:06:00.0: eth0: (PCIe:5.0Gb/s:Width x4)
[    3.719017] igb 0000:06:00.0: eth0: PBA No: 050000-000
[    3.776221] igb 0000:06:00.1: added PHC on eth1
[    3.776227] igb 0000:06:00.1: eth1: (PCIe:5.0Gb/s:Width x4)
[    3.776304] igb 0000:06:00.1: eth1: PBA No: 050000-000
[    3.778356] igb 0000:06:00.1 Glan: renamed from eth1
[    3.883926] igb 0000:06:00.0 Wlan: renamed from eth0

The last is the name in use, in this case Wlan. There should be persistent naming in effect and a line renaming to enosp123 or whatever. Kernel naming in effect results in no changes, so eth0 is eth0. Or in my example a user rule in effect to rename.
So,

Code: Select all

:/etc/network/interfaces.d$ cat eth0.conf
# eth0  enp5s0f0 renamed
allow-hotplug Wlan
iface Wlan inet dhcp

Yes, delete it. If the network works, some other network manager is installed (usually NetworkManager or Wicd, depending on the installed destktop environment) and you don’t need this file.

CwF wrote:To check the name, renaming, ask as root, or sudo

Seriously ? Why not just run «ip link» (which unambigously show current interface names and does not require root privileges) ?

It works! Thank you very much for explaining the process, I deleted /etc/network/interfaces.d/setup, the bogus config file and created a new one with my device name.

setup.conf in the directory etc/network/interfaces.d/with

Code: Select all

allow-hotplug *my device name here* 
iface *my device name here* inet dhcp

reebooted, and the network module loads!

I also obviously removed the commented code

Code: Select all

#sources /etc/network/interfaces.d/*

from /etc/network/interfaces

Yah! kinda…

I’m not perfectly clear what you did, but ok…
/etc/network/interfaces should be unaltered. As a package file it may update and wipe out your settings, likely not.

Code: Select all

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

the line: source /etc/network/interfaces.d/* will load *.conf files if present.
Your settings should go there in a file named
/etc/network/interfaces.d/whatever.conf

Yes that’s essentially what I did. In addition originally I had commented out a part of /etc/network/interfaces

Code: Select all

#this file describes the network interfaces available on your system
# and how to activate the,/ for more information, see interfaces(5)
#sources /etc/network/interfaces.d/*

#the loopback network interface
auto lo
iface lo inter loopback

but now I removed it so it’s

Code: Select all

#this file describes the network interfaces available on your system
# and how to activate the,/ for more information, see interfaces(5)
sources /etc/network/interfaces.d/*

#the loopback network interface

No, /etc/network/interfaces is not a package file, not even a conffile of the package «ifupdown» (which installs the «networking» service and uses /etc/network/interfaces), so user changes won’t be wiped out by a package update. You can check with

Code: Select all

dpkg -S /etc/network/interfaces
dpkg -s ifupdown

So there is absolutely no valid reason to not use it for user-defined network settings. /etc/network/interfaces.d/ is provided mostly for packages so that they can add extra network settings without modifying /etc/network/interfaces.

No, it will load any file present in /etc/network/interfaces.d/*. As a proof, /etc/network/interfaces.d/setup (which does not end in .conf) was loaded and caused the error.

This quote contains multiple typo’s (the,/, sources, inter). I cannot believe this is the original /etc/network/interfaces. Did you copy it by hand ?

ya, said likely not…facility is there for a user file, I simply recommend using it. It is not a *user* file none the less. Without a way, sure, mod it all you want — be tidy and put all the mods in there, or clutter up the .d directory with eth99 rules all separate! I thought I have seen a *.conf preference somewhere, maybe just my preference to help me distinguish *.link files in me notes.

I did not, amazing, not sure what happened? …couple of distraction going on, sorry…this is a typo thread…sorry tired-owl, apparently me too!
Original dated 5/7/2016

Code: Select all

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

hmmm, I obviously bumped some keys, it actually came though the spice channel from another computer! Let’s see, 11/7/2016 on this computer, same contents, my bad!
Sorry to get your autochecker into overdrive! It does matter!

I did type it by hand, sorry for the typos in the config file….

for clearing things up my /etc/network/interfaces is

Code: Select all

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

Next time I’ll make sure to copy it over instead of typing it by hand, I’m writing this from a separate computer. It’s definitely important to have the correct information.
