Package: ausweisapp2 Version: 1.20.2-1 Installing ausweisapp2 on a relatively clean system (ie: no other Qt/QML apps) misses installation of some required dependencies:
$ sudo apt install ausweisapp2 ... $ AusweisApp2 ... default 2020.09.11 11:19:14.860 398030 W unknown(unknown:0) : QQmlApplicationEngine failed to load component default 2020.09.11 11:19:14.860 398030 W unknown(/qml/main.qml:32) : qrc:/qml/main.qml:32:1: module "QtGraphicalEffects" is not installed default 2020.09.11 11:19:14.860 398030 W unknown(/qml/main.qml:30) : qrc:/qml/main.qml:30:1: module "QtQuick" is not installed default 2020.09.11 11:19:14.860 398030 W unknown(/qml/main.qml:28) : qrc:/qml/main.qml:28:1: module "QtQml" is not installed default 2020.09.11 11:19:14.860 398030 W unknown(/qml/main.qml:32) : qrc:/qml/main.qml:32:1: module "QtGraphicalEffects" is not installed default 2020.09.11 11:19:14.860 398030 W unknown(/qml/main.qml:30) : qrc:/qml/main.qml:30:1: module "QtQuick" is not installed default 2020.09.11 11:19:14.860 398030 W unknown(/qml/main.qml:28) : qrc:/qml/main.qml:28:1: module "QtQml" is not installed default 2020.09.11 11:19:14.860 398030 W unknown(/qml/main.qml:32) : qrc:/qml/main.qml:32:1: module "QtGraphicalEffects" is not installed default 2020.09.11 11:19:14.860 398030 W unknown(/qml/main.qml:30) : qrc:/qml/main.qml:30:1: module "QtQuick" is not installed default 2020.09.11 11:19:14.860 398030 W unknown(/qml/main.qml:28) : qrc:/qml/main.qml:28:1: module "QtQml" is not installed ... (and the main app window isn't shown). Installing the following extra dependencies fixes the problem: $ sudo apt install qml-module-qtgraphicaleffects qml-module-qtqml qml-module-qtquick-layouts Thanks for packaging AusweisApp! This makes my life a lot easier. :)
