Latest Raspberry Pi OS needed to use python 3.9.x

[thclark]

Bug report

I updated the Raspberry Pi to use python 3.9.12 using the following instructions (from here):

sudo apt update
sudo apt upgrade
cd ~
mkdir -p python-install && cd python-install
wget https://www.python.org/ftp/python/3.9.12/Python-3.9.12.tgz
tar -zxvf Python-3.9.12.tgz
cd Python-3.9.12
./configure --enable-optimizations
sudo make altinstall
cd /usr/bin
sudo rm python
sudo rm python3
sudo ln -s /usr/local/bin/python3.9 python
sudo ln -s /usr/local/bin/python3.9 python3
cd ~
python --version

Unfortunately when I then install and run the gateway I get the error described here, essentially:

libm.so.6: version `GLIBC_2.29' not found

This forum discusses the problem, concluding that a newer version of the OS is needed in order to run Python 3.9.

Current Workaround

I'm downgrading to python 3.8.13, rather than building my own RPi image!
