mitmproxy binary package in Ubuntu Jammy s390x

 mitmproxy is an SSL-capable man-in-the-middle HTTP proxy. It provides
 a console interface that allows traffic flows to be inspected and
 edited on the fly.
 .
 Also shipped is mitmdump, the command-line version of mitmproxy, with
 the same functionality but without the frills. Think tcpdump for
 HTTP.
 .
 Features:
  - intercept and modify HTTP traffic on the fly
  - save HTTP conversations for later replay and analysis
  - replay both HTTP clients and servers
  - make scripted changes to HTTP traffic using Python
  - SSL interception certs generated on the fly
