Ask HN: Why is Google's sha checksum not matching?

Trying to download https://dl.google.com/dl/cloudsdk/channels/rapid/downloads/google-cloud-cli-darwin-arm.tar.gz from https://cloud.google.com/sdk/docs/install-sdk#installing_the_latest_version and using shasum (on mac) does not give the specified "48b64a1b9003e801cbaedb3d1a7f0d8989c1af207858ea32beea8095b26bd1e9" but a different one.

A colleague confirmed. What's going on?
