Implementation of an ADS-B/Mode-S receiver in GNU Radio

Hi, I’m writing my undergraduate thesis titled ‘‘Development of a Software-defined ADS-B Radio Receiver’’. I’ve downloaded all the necessary drivers for my LimeSDR, as listed on the MyriadRF page. I’ve found a software that should decode ADS-B/Mode-S messages, it’s called gr-air-modes. I’ve followed the instructions on how to install it via https://kb.ettus.com/Implementation_of_an_ADS-B/Mode-S_Receiver_in_GNU_Radio, and it is installed on Ubuntu 18.04., but when I run the modes_gui command in the terminal I get an error:

Traceback (most recent call last):
_ File ‘’/usr/local/bin/mods_gui’’, line 24, in from PyQt4 import QtCore, QtGui, QtWebkit_
ImportError: cannot import name QtWebKit.

When I run the modes_rx command I can see the textual output in the terminal, but it does not give me enough data for my paper. I’ve read about this issue from other users on https://github.com/bistromath/gr-air-modes/issues/98, but no one has offered a solution yet.
Has anyone done something similar or has an idea how to help me?
Best regards!
