Troubleshoot Data Collector upgrade manager upgrade failure and collector bundle download failure on Linux
IT Analytics Data Collector software includes two components - Upgrade Manager and Data Collector.
When 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 11.8 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.
You must have access to:
Data Collector server and Portal server.
Permissions to copy files from and to Data Collector server and Portal server.
