FlightGear 2020.3.0 fails to start launcher on Ubuntu 20.04

[southside]

For the past few weeks I get this failure

and all I see is a blank white window.
I have previously successfully ben using the flightgear-edge ppa.

Can anyone point me at the dependencies I am missing, please? Qt?

I suspect you're missing 'qml-module-qtquick-controls' , based on searching on: https://packages.ubuntu.com/xenial/qml- ... k-controls

[southside]

Thank you qml-module-qtquick-controls2 did the trick

[saiarcot895]

I've added qml-module-qtquick-controls2 as a Recommends for flightgear, so it should get automatically installed in most cases.

I've added qml-module-qtquick-controls2 as a Recommends for flightgear, so it should get automatically installed in most cases.

Note it's only needed for post-2020.2, when we reasied the minimum Qt version to 5.9: 20202.2 and earlier still work down to Qt5.4, hence we can't use QtQuick Controls2

[saiarcot895]

Hmm, ok, I'll need to do something for older versions of Ubuntu then (the ones that don't have Qt 5.9 in the repos).

DAMN! Why is it ALWAYS so broken? I spend more time debugging flightgear than I spend flying. This is BULLSHIT
