Qt.qpa.xcb: could not connect to display

Hello, I want to run wireshark on a container, but i got trouble.

What should i do to connect to display?

Depending on what you’re trying to do, using tshark maybe easier.

thank you, but it’s just a test, i want to know what should i do to run a GUI app on container. Do i need to install vnc4server? Or maybe there’s a simpler solution.

Have a look at

thank you for your help :blush:
