Problems upgrading Python 3.9

[bokub (Boris)]

I solved the problem by install libffi.so.7 manually on my Raspberry Pi.

If it can help someone else, here are the commands:

Python install on Raspberry PI OS

You can install libffi7.so on raspberry OS from source. libffi7 source is Release libffi v3.3 · libffi/libffi · GitHub wget "https://github.com/libffi/libffi/releases/download/v3.3/libffi-3.3.tar.gz" tar zxf libffi-3.3.tar.gz cd libffi-3.3 ./configure sudo make install sudo ldconfig After this the homeassistant can be run under python 3.9.x.
