Many a time for setting your application on fresh ubuntu machine you will be frustrated with the qt unfulfilled dependencies. Once I got this with qtwebkit and I installed all possible plugins like:
apt-get install libqt5multimedia5 libqt5webkit5-dev qtmultimedia5-dev libqtmultimediakit1 libqt5webkit5-qmlwebkitplugin libqt5declarative5 libqtwebkit-dev
Isn’t above all which can be needed for qtwebkit but now still the application gives the same error.
Finally below fixed the issue and it seemed like I never needed all above
apt-get install qtquick1-qml-plugins
I already have the core stuff
|apt-get install qt5-default libqt5declarative5|
|apt-get install libqt5x11extras5|
