Scapy Error

getting this error after a fresh install on Kali 2019.1

Unsure if it's something with my install. Tried different versions of mitm6.

anyways below is the error:

Traceback (most recent call last):

This is a known issue with the latest Scapy that I still need to fix. For now you can work around it by making sure you have v2.4.0 of Scapy: pip install scapy==2.4.0
