Install Python 2 on Ubuntu 20.04 Focal Fossa Linux -

The Python 2 version is no longer a default Python version since Ubuntu 18.04. With a release of Ubuntu 20.04 the Python 2 on a default system installation has been also completely dropped hence you might encounter the following error when executing the python command:
Command 'python' not found
No despair, the Python 2 is not installed by default but it is still available for installation.
