This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Can you please add a little more detail? What did you do, what did you want to achieve and what happened instead? Did you encounter any warning or error messages? Please reproduce them in their entirety in you question. (see How do I ask a good question?) – David Foerster Feb 7 '16 at 18:55

Easy Workaround to enable cable DHCP conectivity

To enable lan via DHCP you can try to modify interfaces file:

sudo nano /etc/network/interfaces

Then add next lines:

auto eth0
allow-hotplug eth0
iface eth0 inet dhcp

Save (ctrl+o), press enter and exit nano (ctrl+x). You can try to restart your network with:

sudo /etc/init.d/networking restart

But if it doesn't work, restart your computer.

Now you will be able to follow the steps provided in the post suggested by kos with a DHCP wired connection
