Hi Frode,

Get the following error when trying to launch fs-uae-launcher:

Is there now a dependency on QT5?

[toxicshadow]

To fix the issue I had to install the following:

qt5-default
qttools5-dev-tools
python3-pyqt5.qtopengl

Guess its a problem detecting that qt5 is not installed

[FrodeSolheim]

The problem was most likely that python3-pyqt5 was installed (so fs-uae-launcher found that), but python3-pyqt5.qtopengl was not installed. Anyway, I'm reverting to prefer pyqt4. Among other things, it wasn't a good idea to change the preference without also changing the package dependencies
