I have a recent install of ubuntu server (all command line) and at the time of the install I was not connected to the internet.

when entering sudo apt-get update I get a bunch of messages saying failed to fetch repos.

I am unable to ping google, askubuntu, or any other site

sudo lshw -class network

indicates both eth0 and eth1 are disabled. 

ifup eth0

results in 

ignoring unknown interface eth0=eth0

is there a way to test the connection from cable modem to machine is ok? (I checked a few times and believe my cable/connections are ok, but I can check again)

thanks bp

  1. Check your network interfaces with: cat /etc/network/interfaces
    1. It should look like something like this:

The loopback network interface auto lo iface lo inet loopback

The primary network interface auto eth0 iface eth0 inet dhcp

  1. sudo service network-manager restart
  2. sudo ifconfig eth0 up
  3. sudo dhclient eth0

Now your connection should be fine.
