Error upgrading Ambari 2.4.2 to 2.5.1 when ambari-server upgrade

Explorer

I'm upgrading Ambari from 2.4.2 to 2.5.1 on HDP 2.4.3, with CentOS 6.

I follow the instructions from https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.1.0/bk_ambari-upgrade/content/upgrade_ambari.ht... .

However when I got to step 9 - ambari-server upgrade I got an error:

Using python  /usr/bin/python
Upgrading ambari-server
Traceback (most recent call last):

Forget to upgrade the ambari-agent on the server host.

As a result an older version of ambari_commons/inet_utils.py was left in python packages: /usr/lib/python2.6/site-packages/resource_monitoring/ambari_commons/inet_utils.py

After upgrading also the agent python package also was also updated.
