As per https://peps.python.org/pep-0394/, the python binary can be one of the following options: - Python 2 - Python 3 - Not exist All of the scripts in libxml2 use 'python', which may not exist. As Python 2 reached EOL on the 1st January 2020, it's safe to move the scripts to use python3 explicitly.
