PIP package scapy-python3 used to provide scapy3k, which was a fork from scapy implementing python3 compatibility since 2016. This package was included in some of the Linux distros under name of python3-scapy. Starting from scapy version 2.4 (released in March, 2018) mainstream scapy supports python3. To reduce any confusion scapy3k was renamed to kamene.
I Have the same issue with you and i remove the scapy from pip and install by pressing sudo apt-get install python3-scapy in Kali Linux
and now works perfectly.If this dont work sorry
sudo python3 ./ufonet --gui
You should use either pip package kamene for scapy3k (see http://github.com/phaethon/kamene for differences in use) or mainstream scapy (pip package scapy, http://github.com/secdev/scapy).
Error importing: scapy lib.
To install it on Debian based systems:
$ 'sudo apt-get install python3-scapy'
I have installed the latest version of scapy (kamene) and im getting this error help
