I was running 16.04 LTS (32 bit)
And decided to upgrade to 20.04 LTS. I removed the drive with 16.04 on it and installed a new SSD. I installed via DVD from downloaded iso. Once it is installed and I reboot there is no network. The ethernet controller does not show under network settings.
If I run sudo lshw -C network I get:



*-network UNCLAIMED
description: Ethernet controller
product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller
vendor: Realtek Semiconductor Co., Ltd.
physical id: 0
bus info: pci@0000:03:00.0
version: 3
width: 64 bits
clock: 33MHz
capabilities: pm msi pciexpress msix vpd cap_list
configuration: latency=0
resources: ioport:ce00(size=256) memory:fdfff000-fdffffff memory:fdff8000-fdffbfff memory:fd400000-fd41ffff


The cable is plugged in and there are lights on both the adapter on the PC and the router.
I have tried reinstalling but same issue. It worked fine with 16.04 and the only things different are the new SSD and the new OS.
I am not very familiar with linux - just a user.
Any help would be most appreciated. Thank you.

The r8168 driver is included in the Ubuntu repositories so you don't need to compile it yourself, so first, try this:



sudo rmmod r8169 r8168
sudo apt-get purge r8168-dkms
sudo modprobe r8169
dmesg | egrep -i 'eth|net|r816'
ifconfig -a


If there were no errors reported by the modprobe or found in dmesg then you should see an ethernet device in the ifconfig output (in addition to the lo device).



If not, try the r8168 driver:



sudo rmmod r8169
sudo apt-get install r8168-dkms
sudo modprobe r8168
dmesg | egrep -i 'eth|net|r816'
ifconfig -a


If you still get no ethernet device, add the output of:



find /lib -name r816*
lsmod
dmesg | egrep -i 'eth|net|r816|error|fail'
ifconfig -a


to the original question.
