Message Broker failing to start following upgrade to 24.7

Hi all,

Upgraded to 24.7 on Ubuntu 22.04 (Release branch) following the upgrade steps. Was already running PG16 so not much needed.

Following upgrade at the pending-setups stage it's failing out restarting the message broker service, see below.

You have 1 pending setups to run
0) carbonio-message-broker.sh

a) execute all
q) quit

See "systemctl status carbonio-message-broker.service" and "journalctl -xeu carbonio-message-broker.service" for details.
Script for message broker terminated with error

Digging into the journals is providing this output;

Any ideas?
