I am upgrading Ubuntu from 12.04 LTS through to 16.04 LTS To do this I have upgraded to 14.04 LTS first Since upgrading to 14.04 I have lost my network and the system cannot even ping its on IP and replies with network unreachable
When i try
ifdown eth0 && ifup eth0
I get the following
ifdown rth0 not configured
/bin/sh: ip: command not found
failed to bring up eth0
When i run ifconfig -a it tells me that eth0 has no ip or other details configured However when i check /etc/network/interfaces it is actually configure correct with
auto lo eth0 eth0:1
iface lo inet loopback
iface eth0 inet static
address 109.x.x.x The IP
netmask 255.x.x.x The netmask
network 109.x.x.x The network
broadcast 109.x.x.x The Broadcast IP
gateway 109.x.x.x The Gateway
Any ideas on what has happened here or how to get around this. Obviously i cannot use apt as i have no network but i have downloaded the 14.04 image onto cd
Many thanks P
