Comment 14 for bug 1772859

I have a clean Ubuntu 18.04 Desktop install with defaults on an HP Envy

I get the same error

WIFI works

PCI Ethernet and USB Ethernet connectors both fail when adding them static or DHCP via Network Manager

I also keep getting the Connection Failed notification, even when only in WIFI mode

its a bug, clean install
