Resolution
When upgrading a high-availability SSB cluster from version 5.3 to 6.0, in some rare cases the primary node does not automatically reboot after clicking Upgrade, reboot master, and shut down slave, but displays the above error message instead.
To solve the problem, click System control > This node > Reboot.
