cannot install aws-sam-cli on macos catalina with brew gdbm not present or broken

Question

Following instructions on https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-install-mac.html:

    (venv) dougbergh@192 de % brew install aws-sam-cli
    Updating Homebrew...
    ==> Installing aws-sam-cli from aws/tap
    ==> Downloading https://github.com/awslabs/aws-sam-cli/releases/download/v0.48.0//aws-sam-cli-0.49.0.sierra.bottle.tar.gz

    curl: (22) The requested URL returned error: 404 Not Found

    Please reinstall gdbm. Sorry :(
    (venv) dougbergh@192 de % python --version
    Python 3.8.1

I can find nothing about installing gdbm...but hopefully the easier path is to resolve the 404 & install from the bottle. Any insights?

Issue with installer; see https://github.com/awslabs/aws-sam-cli/issues/1987. Presumably there will be a fix; a workaround is suggested at that site.
