a) please use "code tags" whenever posting commands AND output. Makes things easier to read. That's "Adv Reply" and the "#" button.

b) Appears that the correct driver for your NIC isn't loaded or the NIC is dead. Please run sudo lshw -C network and post those results, so we can see which driver, if any is being used **and** what chips the NIC uses.

Which says:

I solved this error by deleting /etc/resolv.conf and recreating the symbolic link.


You can do that using the following commands:

sudo rm /etc/resolv.conf
sudo ln -s ../run/resolvconf/resolv.conf /etc/resolv.conf
sudo resolvconf -u

execute those lines one at a time
I added

sudo service network-manager restart

PCI (sysfs)

If that is the only output, then I would guess the NIC is dead.

Here's mine:
