Python3.8 and botocore install issue for docutils

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 (1.19.23 in fact) : https://github.com/boto/botocore/issues/2120

I recomend to upgrade the file to botocore to 1.19.23 & boto3 to 1.16.23.

What you expected to happen: Install should go flowless

BTW. I would not recommend going to 1.10.12 as an intermediate step. There is no reason to do it I think. While there are a number of deprecated things in 1.10.14 (or rather 1.10.15 now), the deprecated functionality continue to work there. So I would strongly encourage you to upgrade straight to 1.10.15.
