I have recently installed ubuntu server 16.04 LTS.a message is coming at the starting time " a start job is running for the raise network " & it takes too much time under offline network. but, when it comes to online makes no problem. how to make faster the startup process without this annoying message if I want to come offline ? and also there is a bridge connection named "virbr0" but not the simple ethernet network, why is this happening ?
need help .
auto eno1
iface eno1 inet dhcp
to
allow-hotplug eno1
iface eno1 inet dhcp

I seem to get the same issue and I also have a bridged network interface, probably from my VirtualBox setup, enp0s31f6:avahi.
My system is ubuntu 16.04 LTS server variant, installed on a laptop, so primary use is as a workstation.
As pr the comments this still applies for ubuntu 20.04 LTS.
The issue is there if the bridged interface is there, not if it's not present, say if VirtualBox has not been started inbetween reboots.
The reason is as in the other answer that this interface lacks init info.
My sollution was to reduce the timeout, and to do so without messing with the base installed networking.services systemd file. This will persist during updates in any package.
sudo mkdir -p /etc/systemd/system/networking.service.d/
sudo bash -c 'echo -e "[Service]\nTimeoutStartSec=20sec" > /etc/systemd/system/networking.service.d/timeout.conf'
sudo systemctl daemon-reload
Follow these steps:
Open /etc/network/interfaces file with gedit or nano:
sudo nano /etc/network/interfaces
Set below text for any interfaces in this file:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
auto wlan0
iface wlan0 inet dhcp
Save the file and reboot
Open /etc/network/interfaces file with gedit or nano:
sudo nano /etc/network/interfaces
Set below text for any interfaces in this file:
auto lo
iface lo inet loopback
Remove any other entries.
It solved for me.
