Fresh install of Ubuntu 20.04 Server. Setup netplan config. However netplan config stops working after a reboot because the interface names change each time for some reason. Setup netplan config to match on mac address and set name, but this still does not work because interface name changes every reboot.
Tried setting grub back to old interface naming convention (eth0) but did not work. Tried changing netplan config to reflect interface names as (ens0) also did not work.
Interface names that change are random and different each reboot.

After updating grub file to reflect GRUB_CMDLINE_LINUX="net.ifnames=0" and starting interface names at eth0, names stayed per netplan config file for 3 reboots then the MAC Addresses started moving between interface names preventing network connection from establishing. I decided to reinstall Ubuntu from scratch and, this time, with a live network connection and enabled all interfaces for dhcp. Below are the netplan config file and interfaces.
