Description

I tried to switch a node from a Rudder server to another. To do it I:

Deleted the node from the initial server
run rudder agent factory-reset on the target node
rm /var/rudder/cfengine-community/ppkeys/policy_server_hash on the node (should be done by the factory reset)

run a first inventory:

agent1:~ # rudder agent inventory
Agent is currently in bootstrap policies, cannot run an inventory. Please download initial policies from the server with command   notice: Trusting new key: MD5=bc0c9963a2cd481f2b9d9521b9958b2f
R: Initial policies have been successfully downloaded from the policy server
ok: Rudder agent policies were updated. first. If problem persists, use WARNING: The file /var/rudder/cfengine-community/last_successful_inputs_update is older than twice 10 minutes, the agent is probably stuck. Purging the CFEngine lock database... Done
FINISH: Rudder agent check ran properly, please look at messages above to see if there has been any error. for diagnostic

run a second inventory which worked

agent1:~ # rudder agent inventory
Rudder agent 6.1.6.rc1.git202010150124

Accept the node on the new server

Try to update my node, which failed:

agent1:~ # rudder agent update
R: *********************************************************************************
* rudder-agent could not get an updated configuration from the policy server.   *
* This can be caused by:                                                        *
*   * an agent key that has been changed                                        *
*   * if this node is not accepted or deleted node on the Rudder root server    *
*   * if this node has changed policy server without sending a new inventory    *
* Any existing configuration policy will continue to be applied without change. *
