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.

Title:
Renaming interfaces using *.link file does not work
Status in systemd package in Ubuntu:
Incomplete
Bug description:
Dear Ubuntu team,
I wanted to use "systemd-networkd" intead of "udev" to rename network
interface like this:
(replace MAC by real one)
########################################
echo '[Match]
MACAddress=12:34:56:78:90:11
[Link]
Name=myname123' | sudo tee '/etc/systemd/network/myname123.link'
########################################
(and reboot)
But it does not work. And it should work based on the systemd
documentation. I googled the issue but I didn't find anything
interesting instead that I should run "update-initramfs -u" but that
didn't help.
I tested that this doesn't work both on Ubuntu Desktop 20.04 and
Ubuntu Server 20.04.
Thank you,
Kind regards,
Ven
