Solve the following python programming problem given the following code:
@ testtools.skipUnless (CONF.aws.run_incompatible_tests, 'Different error code') 
def test_import_invalid_key_pair(self) : 
    keyName = 'Test key' 
    publicKey = 'ssh-rsa JUNK test@ubuntu' 
    def _rollback() : 
        self.client.delete_key_pair (KeyName = keyName) 
self.assertRaises ('InvalidKey.Format', self.client.import_key_pair, rollback_fn = _rollback, KeyName = publicKey, PublicKeyMaterial = publicKey) 

    
    

    Fix the buggy line: self.assertRaises ('InvalidKey.Format', self.client.import_key_pair, rollback_fn = _rollback, KeyName = publicKey, PublicKeyMaterial = publicKey)
