**Apache Airflow version**: 1.10.12 **Environment**: - **Cloud provider or hardware configuration**: AWS - **OS** (e.g. from /etc/os-release): ubuntu 20.04 LTS **What happened**: Trying to install Airflow as recommanded with 3.8 constraint. `pip install "apache-airflow[crypto,password,postgres,aws]"==1.10.12 --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-1.10.12/constraints-3.8.txt"`` I got the error : ``` ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts. We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default. botocore 1.17.43 requires docutils<0.16,>=0.10, but you'll have docutils 0.16 which is incompatible. ``` In the constraint file botocore is set to 1.17.41, but reading this issue it should be 1.18.0 : https://github.com/boto/botocore/issues/2120 I recomend to upgrade the file to botocore to 1.18.0 & boto3 to 1.16.23. **What you expected to happen**: Install should go flowless ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
