ens4 is not a physical devices. It is latched onto ens3 as a virtual device.
I tried to put ens4 on both lines and got error “Cannot find device "ens4"” Kun

If this is verbatim then the issue is that you used ens4 in one line and ens3 in another.

I have configure
auto ens4
iface ens3 inet static
address {my allocated IP}
netmask 255.255.255.252
However, the ifup ens4 command will failed to bring up ens4 interface. And of course when running ampr-run.sh and find_pass.sh will resulted in Setting SO_BINDTODEVICE: No such device.
Any advices on how to set it up on Ubuntu 18?
Thanks
Kun
