Segmentation fault when using Qdronectr application

In the documents: About local controllers - 2.15.1
Qdronectrl is mentioned to control a simulated drone with a keyboard.

I installed the application using:
sudo apt install parrot-tools-qdronectrl

I opened the simulation and then the Qdronectrl application.
The Qdronectrl application crashes after I press the connect button.

This is the log:

Hi @josephhuang08,

Sorry for the delay. We need more details to try to reproduce your problem:

  • Your distribution
  • The model of your drone
  • The version of Qdronectrl
  • If you have a wifi dongle

You can also check the dmesg log just in case.

Thank you in advance.

Axel
