Troubleshoot Data Collector upgrade manager upgrade failure and collector bundle download failure on Linux

NetBackup IT Analytics Data Collector software includes two components - Upgrade Manager and Data Collector.

When NetBackup IT Analytics Portal is upgraded successfully to a newer version, the subsequent Data Collector upgrade may fail with errors like "Collector bundle download failed for 11.6 Premature EOF" or "Upgrade Manager upgrade failed. Exception is : Premature EOF". These errors indicate that upgrade bundle could not be downloaded successfully on to the Data Collector server due to slow network/low bandwidth.

Prerequisites to troubleshoot

You must have access to:

Data Collector server and Portal server.
Permissions to copy files from and to Data Collector server and Portal server.
