### Apache Airflow version 2.6.1 ### What happened We install Airflow in a virtual environment using pip and constraints files, as per the [official documentation](https://airflow.apache.org/docs/apache-airflow/stable/installation/installing-from-pypi.html#constraints-files). We attempted to upgrade from Airflow 2.3.4 to Airflow 2.6.1 on Python 3.10: ``` pip install "apache-airflow[amazon, snowflake, slack, postgres]==2.6.1" --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-2.6.1/constraints-3.10.txt"; ``` However, we encounter the following error: ``` ERROR: Cannot install apache-airflow[amazon,postgres,slack,snowflake]==2.6.1 because these package versions have conflicting dependencies. The conflict is caused by: apache-airflow[amazon,postgres,slack,snowflake] 2.6.1 depends on importlib-metadata<5.0.0 and >=1.7; python_version < "3.9" The user requested (constraint) importlib-metadata==6.6.0 To fix this you could try to: 1. loosen the range of package versions you've specified 2. remove package versions to allow pip attempt to solve the dependency conflict ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/topics/dependency-resolution/#dealing-with-dependency-conflicts ``` When setting up an entirely new virtual environment and attempting install from scratch (both with and without providers) using the same command, the install finishes, but a similar error surfaces: ``` ERROR: apache-airflow 2.6.1 has requirement importlib-metadata<5.0.0,>=1.7; python_version < "3.9", but you'll have importlib-metadata 6.6.0 which is incompatible. ``` ### What you think should happen instead The constraints file should be able to install all dependencies without resolution-errors. ### How to reproduce Create and activate a new virtual environment on Python 3.10: ``` python3 -m venv airflow26 source ~/.venv/airflow26/bin/activate ``` Attempt the Pip install of Airflow 2.6.1 on via the 3.10 constraints file: ``` pip install "apache-airflow==2.6.1" --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-2.6.1/constraints-3.10.txt"; ``` ### Operating System Ubuntu 20.04 ### Versions of Apache Airflow Providers This error arises regardless of providers specified. ### Deployment Virtualenv installation ### Deployment details n/a ### Anything else This appears to be a recent issue with 2.6. We have never encountered this issue before with previous Airflow and Python versions. ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
