Hi!
That scapy version doesn’t work as expected anymore as the offical scapy library now supports python3, So run:

pip3 unistall scapy
pip3 unistall scapy-pyhton3
pip unistall scapy
pip unistall scapy-pyhton3

pip install scapy
pip3 install scapy

If any of the unistall commands throw an error saying it couldn’t unistall because there’s no such package just ignore it.

Let me know how it goes!
