Hi, As a part of the Astronomer Airflow Training Course provided by my company, trying to set up Airflow using Astronomer.
But couldn’t resolve this error during astro dev start:
ERROR: failed to solve: process “/bin/bash -o pipefail -e -u -x -c if grep -Eqx ‘apache-airflow\s*[=~>]{1,2}.*’ requirements.txt; then echo >&2 "Do not upgrade by specifying ‘apache-airflow’ in your requirements.txt, change the base image instead!"; exit 1; fi; pip install --no-cache-dir -q -r requirements.txt” did not complete successfully: exit

Any help would be appreciated!. Thanks.

Hi @vigneshvikiis64,

Welcome to the Astro Community, Glad to see you using the Astro CLI.

Per the error message (NewConnectionError) provided It looks like a connection cannot be established from your terminal to download and install the required packages.

Please check your network connectivity and see if your system isn’t behind any Firewall or VPN that would be restricting this connectivity.

I hope this helps!
