       After enabling the debug-mode, execute the following command to get the information you need
       to start debugging:
-        `juju run-action get-debug-mode-information <unit name> --wait`
+        `juju run-action <unit name> get-debug-mode-information --wait`
 
       The previous command returns the command you need to execute, and the SSH password that was set.
