@Shelton  After the apply of the workaround on the file /var/lib/ambari-agent/cache/custom_actions/scripts/remove_previous_stacks.py, I succeeded to execute the API request but there's no effect : the directory of the old version hasn't been removed on the servers of the cluster, and the results of the API queries GET http://localhost/api/v1/clusters/<cluster_name>/stack_versions,  http://localhost/api/v1/clusters/<cluster_name>/stack_versions/<id_oldversion>,  are the same.     ...

@Shelton  In order to remove or modify the symlinks that point to the old version, I have executed the command '/usr/bin/hdp-select set all 3.1.4.0-315' on all servers of the cluster. After that, I have relaunch the API request, and I get a new error that I think I can fix with the workaround suggested before in this thread Traceback (most recent call last): File "/var/lib/ambari-agent/cache/custom_actions/scripts/remove_previous_stacks.py", line 119, in <module> RemovePreviousStacks().execute() File "/usr/lib/ambari-agent/lib/resource_management/libraries/script/script.py", line 352, in execute method(env) File "/var/lib/ambari-agent/cache/custom_actions/scripts/remove_previous_stacks.py", line 49, in actionexecute self.remove_stack_version(structured_output, low_version) File "/var/lib/ambari-agent/cache/custom_actions/scripts/remove_previous_stacks.py", line 54, in remove_stack_version packages_to_remove = self.get_packages_to_remove(version) File "/var/lib/ambari-agent/cache/custom_actions/scripts/remove_previous_stacks.py", line 77, in get_packages_to_remove all_installed_packages = self.pkg_provider.all_installed_packages() AttributeError: 'AptManager' object has no attribute 'all_installed_packages'   ...

@Shelton  Yes, I tried this workaround, and I still get this error : Traceback (most recent call last): File "/var/lib/ambari-agent/cache/custom_actions/scripts/remove_previous_stacks.py", line 118, in <module> RemovePreviousStacks().execute() File "/usr/lib/ambari-agent/lib/resource_management/libraries/script/script.py", line 352, in execute method(env) File "/var/lib/ambari-agent/cache/custom_actions/scripts/remove_previous_stacks.py", line 49, in actionexecute self.remove_stack_version(structured_output, low_version) File "/var/lib/ambari-agent/cache/custom_actions/scripts/remove_previous_stacks.py", line 53, in remove_stack_version self.check_no_symlink_to_version(structured_output, version) File "/var/lib/ambari-agent/cache/custom_actions/scripts/remove_previous_stacks.py", line 93, in check_no_symlink_to_version raise Fail("{0} contains symlink to version for remove! {1}".format(stack_root_current, version)) resource_management.core.exceptions.Fail: /usr/hdp/current/ contains symlink to version for remove! 3.1.0.0-78 It seems that it fails because there are still symink to the old version in the directory /usr/hdp/current (at least on the server where ambari-server is hosted) : root@server-01:~# ls -l /usr/hdp/current | grep 3.1.0.0-78 lrwxrwxrwx 1 root root 25 Jul 28 06:27 atlas-server -> /usr/hdp/3.1.0.0-78/atlas lrwxrwxrwx 1 root root 31 Jul 28 06:27 hadoop-hdfs-datanode -> /usr/hdp/3.1.0.0-78/hadoop-hdfs root@server-01:~# ls -l /usr/hdp/current | grep 3.1.4.0-315 lrwxrwxrwx 1 root root 26 Jul 28 10:44 atlas-client -> /usr/hdp/3.1.4.0-315/atlas lrwxrwxrwx 1 root root 27 Jul 28 10:51 hadoop-client -> /usr/hdp/3.1.4.0-315/hadoop lrwxrwxrwx 1 root root 32 Jul 28 10:51 hadoop-hdfs-client -> /usr/hdp/3.1.4.0-315/hadoop-hdfs   ...
