I tried to re-create deployment-kafka-logging01 in deployment-prep with Debian Trixie and Kafka 3.7 to test the new versions, but for some reason puppet doesn't work. I noticed that puppet is not installed correctly, since we don't support 8:
elukey@deployment-kafka-logging01:~$ dpkg -l | grep puppet ii puppet-agent 8.10.0-5 all configuration management system, agent
At the moment the Beta logs are down, I'll prioritize this on Monday. Sorry for the inconvenience!
