Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

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

My file originally did not have the eth0 lines, only the lo lines. Might that be why I'm having trouble connecting to the wireless? –  Adina G Feb 24 '13 at 4:20
    
@AdinaG I can't tell for sure. If you're still having any troubles with Ubuntu, maybe it's worth posting another question. –  Desmond Hume Feb 24 '13 at 7:53
