I experiencing the same problem. My two Ethernet interfaces does not get
renamed. I want to accomplish the following.
eth0 => eth1
eth1 => eth0
Basically switching names between the Ethernet interfaces.
I had the same exact setup on 18.04 which worked.
You can find some information about my system below. Please let me know
if I should provide more information.
