Post subject:  Setting up static and private ip on Ubuntu 14.04

Hi,

The following configuration works on ubuntu 12.04, I was able to setup static and a private ip addresses, however when I try the same thing on ubuntu 14.04, I get the following error:

RTNETLINK answers: File exists
Failed to bring up eth0.
RTNETLINK answers: File exists
Failed to bring up eth0:1.

Could you please give me a hint about this? I could not find anything about this on the web.

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

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
# auto eth0
# iface eth0 inet dhcp
auto eth0 eth0:1

# The address and gateway are necessary.
# The netmask is taken automatically from the block.
# Example: /24 is considered to be a public IP address: netmask 255.255.255.0
iface eth0 inet static
address 212.71.233.178/24
gateway 212.71.233.1

# This is a private IP address. Private IPs do not have a gateway (they are not$

# Example: /17 is considered to be a private IP address: netmask 255.255.128.0
iface eth0:1 inet static
address 192.168.132.42/17

Thanks in advance
