We cannot do this for two reasons: 1) QGtkStyle is abandoned and unsupported upstream. 2) The goal is to remove GTK+ 2 from the default installation (and later from Ubuntu archive).

For Qt5 applications to pick up the GTK+ style, qt5-style-plugins must be included into the default installation and “export QT_QPA_PLATFORMTHEME=gtk2” must be provided. Original bug description: Since I upgraded to Qt 5.7.1, Qt5 apps stopped picking up the Ubuntu (GTK+, I presume) theme, and look very Windowsy. I have qt5-gtk-platformtheme installed, and I tried forcing it by setting QT_QPA_PLATFORMTHEME, but to no avail.
