Ubuntu – Booting system without full network configuration


I was trying to solve internet problems, and seem to have made things worse: Now when I start the computer it gets stuck on "Booting system without full network configuration".

Does anyone know how to make it unstuck?

Alternatively: It got messed up when I changed the contents of /etc/network/interfaces, so presumably would work again if I changed it back. How can I edit this file during boot?

I'm using Ubuntu 12.10.

  • After you see "Booting system without full network configuration" press CtrlAltF1. It should get you to the shell prompt. Use a shell text editor to change /etc/network/interfaces.

    For example, with nano text editor it would be

    sudo nano /etc/network/interfaces

    Press CtrlO and CtrlX to save changes and exit nano after you've done with it. (Pressing CtrlX and then N discards changes) sudo reboot restarts the system.

    The default contents of the /etc/network/interfaces file look something like this:

    # The loopback network interface
    auto lo
    iface lo inet loopback
    # The primary network interface
    auto eth0
    iface eth0 inet dhcp
