TP of Linux on ARM desktop in 6.7.0 cannot be used "out of the box"

I did this test on April 5th and on Ubuntu 22.04 running standard Ubuntu desktop and on RPi5.

In this iteration, a minimal set of packages is available as planned.

After installing the dependencies listed on https://doc.qt.io/qt-6/linux.html, QtC 13 still did  not launch due to missing libdouble-conversion. Manual installation of libdouble-conversion-dev helped to resolve dependencies, but QtC 13 still did not launch and  complainied that it cannot launch as long as platform "wayland" is not preset. After using "-platform wayland", QtC 13 launched but filled the console with multiple warnings.

As I do not know all the QtC insights, I stopped here and thought, I would better wait for the next update.
