Issue	Solution	Tasks	Alternative(s)
ActiveGate/Oneagent pod won't pull the image / is not starting anymore.	Check in the Cluster management console the installer packages for ActiveGate.	Make sure to have the correct version available (not excluded). The ActiveAGate/OneAgent version has to be -1 from the Managed cluster version.	Raise a support ticket.

This situation can occur if you're trying to do a managed cluster update, for example from 1.260 to 1.262 and it fails. During the upgrade process, you manually exclude ActiveGate/OneAgent installer with version 1.259.

So if the upgrade will fail, and you're still running as in the example managed cluster 1.260 and ActiveGate installer 1.259 has been excluded, you will see following message:

The solution for this is to go to Cluster Management console and make the ActiveGate/OneAgent installer available once again and then check the status of the ActiveGate/OneAgent pod.

If the issue persists though, please raise a support ticket and we'll assist you.
