Compatibility_Ubuntu_GnuRadio_Python

Hello,

I have installed GnuRadio 3.10.1.1 and Python 3.10.4 on Ubuntu 22_04

and I run into a problem:

 

There is only a very simple flowgraph:

QT GUI Toggle Switch --> QT GUI LED Indicator

 

At runtime, there is an error in modul:

"/usr/lib/python3/dist-packages/gnuradio/qtgui/ledindicator.py", line 79

As I can see, there is a type mismatch between float and whatever?

Has anybody an idea what goes wrong and how can I fix it?

Thanks

Karlheinz Kemna
