We have been using airflow in our prod environments since last 2 years and are on 1.7.1.3 version.
Lately, when I tried to do pip install airflow==1.7.3.1, it failed to install and verbose log helped in tracing the artifact location - https://pypi.org/simple/apache-airflow/
I see that 1.7.1.3 version of airflow is removed from there.
Is there any other repository which hosts the artifact? If no, which other alternative do I have to have it installed using pip?
Note that the pip name for Airflow is now apache-airflow, as for the version, the 1.7.1.3 tag is still available from the Github repository. To install it you'll need to clone the repository, checkout the specific tag, and then do a pip install against the repository folder:
$ git clone https://github.com/apache/incubator-airflow.git

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:
git checkout -b <new-branch-name>
