Ethernet Network not showing or connecting in Ubuntu 17.04

I updated from 16.04 to 17.04 a couple days ago. After doing so I found that when I connect my Ethernet cable, it doesn't connect or show connection as it did in 16.04. I Have an HP-15 laptop. I checked for drivers in update area, but it didn't find anything related to Ethernet network.

Here is what I did: To do this - in a terminal:

sudo nano /etc/NetworkManager/NetworkManager.conf

change the line managed=false to managed=true

Save, stop and start network manager:

sudo service network-manager restart

But still have the problem.

It looks like it tries to connect to LAN wired connection but then goes directly to WiFi and connects, then doesn't show any Ethernet connection like it did in 16.04. Any help would be appreciated. I'm almost ready to revert to 16.04

According to this bug report, the solution is to add a missing configuration file to NetworkManager, then to restart it.

It worked for me :

sudo touch /etc/NetworkManager/conf.d/10-globally-managed-devices.conf
sudo systemctl restart NetworkManager

Open an Terminal window. There are many different methods for this. The easist is to Alt + Ctrl + T at the same time.

Step 1 Type in or copy this command: sudo touch /etc/NetworkManager/conf.d/10-globally-managed-devices.conf Then press the Enter key. Now type in your user password and press the Enter key again.

Step 2 Do the same for this command: sudo systemctl restart NetworkManager

I entered this into terminal:

sudo touch /etc/NetworkManager/conf.d/10-globally-managed-devices.conf

entered and then rebooted and it is there.
