I have installed qt5-doc, but documentation for QtQuick is still missing(note that only qtquick is missing, the rest is there, even qt quick controls)
The error is:
Error loading: qthelp://org.qt-project.qtqml.521/qtquick/qtquick-index.html
Note that /usr/share/doc/qt/qtquick/ folder is not empty and qtquick-index.html exists.
