Original report

I'm struggling with an issue with the virtualkeyboard of Qt using Pyside6 :

I have tried my app on a RaspberryPi with debian and no issue at all with the keyboard, with just a pip install pyside6, everything is working fine.

But on a regular PC with Ubuntu (22 and 24), after installing pyside6 with pip install pyside6 , I keep getting this error :
 qrc:/qt-project.org/imports/QtQuick/VirtualKeyboard/InputPanel.qml: No such file or directory
The workaround was to make a downgrade to Pyside 6.7.3 and then everething is working fine.
