sadly, I get `qt.qpa.xcb: could not connect to display :1.0
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: minimal, xcb.` afterwards. any idea how to fix this?

Are you using WSL ?

[@jrM5492]

@@Klox-my7yb VMware Ubuntu22.04, tried all solutions and couldn’t install qt 6, and finally settled with qt5. Very strange.

[@manuelanatoliyarciasalmero9095]

The same QT6 installer told me that you should install this: apt install libxcb-cursor0 libxcb-cursor-dev
