[grantav]

Apache Airflow version: 2.0.1

Kubernetes version (if you are using kubernetes) (use kubectl version):

Environment:

• Cloud provider or hardware configuration:
• OS (e.g. from /etc/os-release): "elementary OS 5.1.7 Hera"
• Kernel (e.g. uname -a): "Linux 5.4.0-65-generic TimeSensor does not trigger #73~18.04.1-Ubuntu SMP Tue Jan 19 09:02:24 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux"

What happened:

When running the following command:
./breeze start-airflow --python 3.8 --install-airflow-version 2.0.1 --backend postgres --postgres-version 9.6
If I choose to rebuild the CI image, I get the following error:
Please confirm rebuild image CI-python3.8. Are you sure? [y/N/q] y .... airflow-providers-zendesk WARNING: You are using pip version 20.2.4; however, version 21.0.1 is available.

What you expected to happen: The image would build accordingly
