On Xubuntu 17.04, KTouch opens with an empty page. I can see the following message if I start it from a console: file:///usr/share/ktouch/qml/main.qml:19:1: module "QtQuick" is not installed import QtQuick 2.4 ^ From what I can see, QtQuick 5.7.1 is installed. I can also see dependencies in the package for libqt5quick5 (>=5.6.1)
This seems to be packaging issue. Please file a bug at your distributions bug tracker. I am not involved with the Xubuntu project. In fact I don't even use it so I can't analyze the problem myself.
ok thank you, I thought the packages would've been handled by the KDE-Edu team. I filed a report on Ubuntu.
