Hi there,

Thank you for reporting this.

This is going to be beyond the scope of the tutorial. However here is how you could install a specific version if needed:

First, install the required libraries:

sudo apt-get install libssl-dev openssl make gcc

Then choose the specific Python from here:

https://www.python.org/ftp/python/

After that go to the /opt directory and download the archive of the specific version:

cd /opt
wget https://www.python.org/ftp/python/3.9.2/Python-3.9.2.tgz

Extract the archive:

tar xzvf Python-3.9.2.tgz

Then cd into the directory:

cd Python-3.9.2

And finally, compile the new version:

./configure
make
make install

Finally you can create a symlink for that specific Python version so that you could use the binary from anywhere:

sudo ln -fs /opt/Python-3.9.2/Python /usr/bin/python3.9

Then you could check if the python3.9 version is available:

python3.9 --version

Hope that this helps.
Regards,
Bobby
