Unable to install latest version of SAM

[shivushedad]

We were trying to update EphemeralStorage on our Serverless function.

This is supposed to work based on https://github.com/aws/serverless-application-model/issues/2361 and documentation here.

However, on our GHA workflow when using latest setup-sam action, it only installs 1.41. Due to this down the line when using SAM deploy we get an error property EphemeralStorage not defined for resource of type AWS::Serverless::Function (which per the documentation should be valid)

Workflow step:

- name: Setup AWS SAM
  uses: aws-actions/setup-sam@v2

We also tried to use the version parameter to force it to download version 1.48 and got this error:

Are you using a self-hosted runner? Perhaps it's using a PyPI mirror that doesn't include the latest versions?

The versions are there in the public repository:

Yes we are using self hosted runners as we are behind a corporate network.

Okay, I'm assuming the issue is due to using a PyPI mirror that doesn't include latest package versions, in which case you'll have to ask the repository admins to update.

You can confirm by checking that pip.conf (you can get the list of locations by running pip config list -v) overrides the default PyPI repository with key index.

Closing this, assuming issue was with using a non-default PyPI mirror in the runner. Let me know if the issue persists.
