Realtek ethernet driver issue, network unclaimed, ubuntu 18.04

Question

i'm getting error network UNCLAIMED, and i see through the forums that it states the drivers. well, my kernel is 5.3.0-20-generic, and it states when i try to install the drivers, its the latest...and its not working. do i need to downgrade to the prior version of the drivers or wait till the create it for this kernel? funny thing is my wireless interface is working...any help in the right directions, thanks.

$ sudo lshw -C network

Solution

You don't need r8168-dkms with new kernels.

Remove it by sudo apt purge r8168-dkms and the adapter will be managed by the kernel in-tree module.

Would you be willing to post an answer explaining how you did that? I believe that may help others who find this by searching.

How do you install it if you do not have internet access?

Hi @qualia, after you do this how do you actually get the error (UNCLAIMED) to go away? Is there anything else? I followed your instructions and rebooting did not seem to fix.
