      logger.error <<~EOL
        It looks like you have the AZURE_STORAGE_ACCESS_KEY environment variable set.
        It may be the incorrect key for the storage account: #{@info['storage_account_name']}
        Try unsetting it:

            unset AZURE_STORAGE_ACCESS_KEY

        When the environment variable is not set, this library will try to fetch the key for you.
        Or you can try setting the correct key.
      EOL
    else
      logger.error <<~EOL
        The fetched storage access key did not seem to authenticate successfully.
        Try setting the AZURE_STORAGE_ACCESS_KEY environment variable with access to the storage account: #{@info['storage_account_name']}
      EOL
    end
    # Common message
    logger.error <<~EOL
      One way to get the key is with:

          az storage account keys list --account-name #{@info['storage_account_name']} --resource-group #{@info['resource_group_name']}

      Then you can set it:

          export AZURE_STORAGE_ACCESS_KEY=[replace-with-value]
    EOL
    exit 1
  else
    raise
  end
