What problem was encountered?

This code doesn’t work anymore in 2.0.0:

        # create a template sas token for the container
        service = BlockBlobService(account_name=storage_account_name,
                                   # don't sign the template with the storage account key use key 00000000
                                   account_key='00000000')
        permissions = ContainerPermissions(read=True, write=True, delete=True, list=True)
        temp_token = service.generate_container_shared_access_signature(container_name='blobcontainer',
                                                                        permission=permissions,
