try adding the following in /etc/network/interfaces :
# Wired adapter #1
allow-hotplug eth0
iface eth0 inet dhcp
it could also be an issue with the driver. there's a post on armbian's forum, that discussed the eth0 driver not working after the kernel update to 5.8. My A64+ is running Armbian and has a similar problem, so I just use the wifi connection.
