Hi, I execute the upgrade/installation of ambari 2.4.2 to 2.5.2 and I have an issue when I want to launch "ambari-server upgrade". I obtain the following message :bugambari.jpg [root@idlvsrv514 ~]# ambari-server upgrade Using python /usr/bin/python Upgrading ambari-server Traceback (most recent call last): File "/usr/sbin/ambari-server.py", line 40, in <module> from ambari_server.serverUpgrade import upgrade, upgrade_stack, set_current File "/usr/lib/python2.6/site-packages/ambari_server/serverUpgrade.py", line 51, in <module> from ambari_server.setupMpacks import replay_mpack_logs File "/usr/lib/python2.6/site-packages/ambari_server/setupMpacks.py", line 30, in <module> from ambari_commons.inet_utils import download_file, download_file_anyway ImportError: cannot import name download_file_anyway I'am blocked.

Hi, in the documentation (https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.0/bk_support-matrices/content/ch_matrices-ambari.html#ambari_stack) for the upgrade of Ambari (2.4.2 to 2.5.2 or 2.6) and the python version needed (Software Requirements), the version of python for CentOS 6 is not indicated.
