Could not load the Qt platform plugin "xcb" on Ubuntu24.04

[khadkevich]

Hello,

On my Ubuntu24 I have successfully made the very first step and built the environment by running
./build_dockerized.sh
But I am stuck on the next step. When I execute
./run -q
I've got the following error:

non-network local connections being added to access control list
qt.qpa.xcb: could not connect to display :0
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: vnc, linuxfb, minimal, minimalegl, eglfs, xcb, offscreen, vkkhrdisplay.

All my attempts to resolve it by applying ALL solutions which I have found on the Internet failed unfortunately.
Could you please provide a working one for Ubuntu24?

Ok, we'll investigate and fix this.
