Ethernet Not Working, Intel e1000e 82578DC rev 06

[jerryc]

No suitable device was found. The issue is with the driver not working/wrong/ or not installed correctly/ or with the device permissions i/e Network Manager permissions to the device. Network Manager seems to be working properly though.
You can check your /etc/network/interfaces file for eth configuration though I expect all is already there properly.

Nope, /etc/network/interfaces only had:

Code:

auto lo
iface lo inet loopback

So, I added:

Code:

# manual additions to get ethernet to work
auto enp0s25
allow-hotplug enp0s25
iface enp0s25 inet dhcp

Then ran:

Code:

sudo ifup enp0s25

And got:

Code:

Even though we're not there yet, I think this is progress.

Thank you for your help.
