AusweisApp2 launches without UI, logs errors about missing QT Modules

[Leopold Seckendorff]

initial installation via `sudo apt install ausweisapp2` caused the app to start without a UI. the sys tray icon was showing and the app could be exited. the log file yielded the following information:

```

the bug could be resolved by installing the following packages:

`sudo apt install qml-module-qtgraphicaleffects qml-module-qtqml-models2 qml-module-qtquick-controls2 qml-module-qtqml-models2 qml-module-qtquick-layouts`

note the layouts package is required as well, although not in the initial log file.

+1 Thats the only thing stopping this from working on Linux.

Shouldnt these packages typically be dependencies of this one ?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Leopold Seckendorff (poddus)]

seems like a simple fix of adding the dependencies to the dist

[André Klitzing (misery)]

That should be fixed by latest backport in Debian.
https://packages.debian.org/buster-backports/ausweisapp2

[Ahmad Gharbeia أحمد غربية (gharbeia)]

I found out that installing qml-module-qtgraphicaleffects and qml-module-qtquick-layouts solves the issue and now AusweisApp2 shows its interface when launched in Ubuntu 20.04

I fixed it in my backport PPA: https://launchpad.net/~misery/+archive/ubuntu/ppa/+packages
