Solve the following python programming problem given the following code:
@ mock.patch.object (seamicro, '_get_server', autospec = True) 
def test_set_boot_device_fail(self, mock_get_server) : 
    def fake_set_boot_order(self, **kwargs) : 
        raise seamicro_client_exception.ClientException (http_client.INTERNAL_SERVER_ERROR) 
boot_device = 'pxe' 
    server = self.Server (active = 'true') 
    server.set_boot_order = fake_set_boot_order 
    mock_get_server.return_value = server 
    with task_manager.acquire (self.context, boot_device.info ['uuid'], shared = False) as task : 
        self.assertRaises (exception.IronicException, task.driver.management.set_boot_device, task, boot_device) 
mock_get_server.assert_called_once_with (self.info) 

    
    

    Fix the buggy line: with task_manager.acquire (self.context, boot_device.info ['uuid'], shared = False) as task :
