Does not start, qt problem. Linux Debian

[sunsetsandplants]

System:

Operating System: Debian GNU/Linux bookworm/sid
Kernel: Linux 5.19.0-2-amd64
Architecture: x86-64

Installation seemed to go fine, but when I try to run qualcoder I get the following error message. Any clues?

Downloads/QualCoder-master# qualcoder
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, xcb, offscreen, vkkhrdisplay, wayland-egl, minimal, minimalegl, wayland, eglfs, linuxfb.

Perhaps try this?

sudo apt install libxcb-util1

Thanks for the swift suggestion.

Unfortuneately:

libxcb-util1 is already the newest version (0.4.0-1+b1)

There are other suggestions here, to do with setting QT_PLUGIN_PATH:

On Debian 12 I had the same problem and I solved it by installing a library:

sudo apt install libxcb-cursor0

@mafes1 Thank you for the feedback. How did you know that library was the one to install?
