Resolución
Workaround:
- Perform a "system switchover" command to failover to the second supervisor. Wait until the command completes. Use the command "show system redundancy status" to confirm the action completes.
- Perform a second "system switchover" command to go back to the previously active supervisor where the upgrade code currently resides.
- Rerun the "install all" command and upgrade should complete.
