I am the reporter of the duplicate bug #958190. On my system qml-module-qt- labs-platform is installed.
With "export QML_IMPORT_TRACE=1" I get: QQmlImports(qrc:/qml/main.qml)::addLibraryImport: "Qt.labs.platform" 1.1 as "" QQmlImports(qrc:/qml/main.qml)::importExtension: loaded "/usr/lib/x86_64- linux-gnu/qt5/qml/Qt/labs/platform/qmldir" QQmlImportDatabase::registerPluginTypes: "Qt.labs.platform" from "/usr/lib/ x86_64-linux-gnu/qt5/qml/Qt/labs/platform" QQmlApplicationEngine failed to load component qrc:/qml/main.qml:31 module "Qt.labs.platform" version 1.1 is not installed The file /usr/lib/x86_64-linux-gnu/qt5/qml/Qt/labs/platform/qmldir exists. Maybe its a problem with the version? Ausweisapp2 asks for 1.1. But how do I know, which version is provided by the debian package? qt version is 5.12.5 but I thinks that doesnt help.
