### What you think should happen instead
The upgrade process should finish without errors
### How to reproduce
Install the latest version of Python 3.9 on Ubuntu 20.04 lts
Install Airflow steps
`AIRFLOW_VERSION=2.3.1
PYTHON_VERSION="$(python3 --version | cut -d " " -f 2 | cut -d "." -f 1-2)"
CONSTRAINT_URL="https://raw.githubusercontent.com/apache/airflow/constraints-${AIRFLOW_VERSION}/constraints-no-providers-${PYTHON_VERSION}.txt";
pip3 install "apache-airflow[celery,redis,mysql,amazon]==${AIRFLOW_VERSION}"
--constraint "${CONSTRAINT_URL}"
`
