mitmproxy is not working on Kali Linux (no attribute 'WSGIAdapter')

See original GitHub issue

Hi guys,

I am on Kali Linux (4.19.0-kali5-amd64 #1 SMP Debian x86_64 GNU/Linux) and I never used mitmproxy before, it was pre-installed by default.

Steps to reproduce the problem:

Running mitmproxy from command line

System information

This is the output of the console :

Traceback (most recent call last):
  File "/usr/bin/mitmproxy", line 11, in <module>
    load_entry_point('mitmproxy==4.0.4', 'console_scripts', 'mitmproxy')()
