repmgr standby switchover -f /etc/postgresql/12/main/repmgr.conf --dry-run

WARNING: the following problems were found in the configuration file:

It is a Two Node Cluster
Primary Node: Node1
Standby Node: Node2
I tried to run repmgr standby switchover -f /etc/postgresql/12/main/repmgr.conf --dry-run on StandBy Node and recevied SSH not enabled. I checked SSH status it is active and i am able to ssh to Primary from the StandBy Node.

Did you provide SSH Keys for passwordless logins between the two nodes for the postgres/repmgr user?

Hello i have the same problem:
$ repmgr cluster show

HINT: ensure at least one node is registered

@castlhe this is unrelated to the original post. Please remove the cluster parameter to remove the warning message and check that you have the repmgr database configured correctly and you've registered all the nodes via repmgr primary/standby register
