Hi,
I'm on Fedora 30. Just installed calibre with the suggested wget.
When running calibre I too get the message:
QGtkStyle could not resolve GTK. Make sure you have installed the proper libraries.

I have no interest in themes.
It is suggested to run calibre with no QT themeing.

I am QT ignorant so please explain how to do that.

Thank you,
Dan
