I just installed ubuntu 12.04.1 alternative install (for raid 0 on some disks). I Have some problems with the net. I'm at school, we use cable, and it got IPv6.

If I run ifconfig eth0 heres my output:

eth0      Link encap:Ethernet  HWaddr e0:cb:4e:87:ff:db  
          inet addr:128.39.194.217  Bcast:128.39.194.223  Mask:255.255.255.224

          inet6 addr: 2001:700:1100:8008:48f7:c23:1d87:da6c/64 Scope:Global

          Interrupt:68 Base address:0x6000

My /etc/network/interfaces look like this:

# 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
# NetworkManager#iface eth0 inet dhcp
# NetworkManager#hostname 2001:700:1100:1::4
# This is an autoconfigured IPv6 interface
iface eth0 inet6 auto

(I had to remove the hash tags, because of the BIGFONT i get on ask ubuntu)

The "network manager" says that I'm not connected.

Let me know if you need any more information. :)

Ok so I have a way better answer then I had before.

How about we try this.

Open a terminal.

gksu gedit /etc/rc.local

Add: sudo dhclient eth0 like so.

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
sudo dhclient eth0
exit 0

Save & Close. Reboot and should work.

Your NetworkManager has for some reason commented out the necessary configuration to make DHCP pick up an IPv4 address. Maybe it was a bug or you configured it to turn off IPv4? This is why it isn't working.

# NetworkManager#iface eth0 inet dhcp

To resolve the problem, simply restore the configuration.

iface eth0 inet dhcp

Also check your NetworkManager configuration and make sure you didn't disable IPv4 on the interface.

You can create a launcher for your command then put it in the autostartup applications

To create a launcher:

Using ALT+F2 type

gnome-desktop-item-edit --create-new ~/Desktop

This will launch the GUI Dialog and create a launcher on your Desktop:

enter image description here

Prerequisites

gnome-desktop-item-edit is installed automatically if you have installed gnome-shell/gnome-fallback. It is also installed automatically if you have previously installed gnome-tweak-tool.

Alternatively, you can install the old gnome-panel without much of the bulk:

sudo apt-get install --no-install-recommends gnome-panel
  • Come on! You also need to setup a passwordless sudo for that command. Those startup applications are loaded only after login and this is not what the user wants. – maxadamo Oct 25 '17 at 18:52

uess it is back to the drawing board.This download is faulty. /etc/Network does not exit. None of the solutions presented will work. I guess it is back to thee shopping for a package that will install on teh Pi 3B+.
