OK, found a workaround. From the 24.04 system, make sure to systemctl stop rabbitmq-server.service systemctl stop epmd.service
make a safety copy/backup of /var/lib/rabbitmq Repeat the following two podman commands for 3.9 , 3.10, and 3.11: In one shell run (replace 127 and 138 with uid and gid of rabbitmq on your system and make sure that $HOST is set to your hostname, must be the same as your host for things to work, the -p ports are not needed, but a way to make sure no other daemon is running) podman run -it --rm -v /var/lib/rabbitmq:/var/lib/rabbitmq --uidmap=0:0 --uidmap=u999:127 --gidmap=0:0 --gidmap=g999:138 -p 5672:5672 -p 15672:15672 --name $HOST -h $HOST docker.io/library/rabbitmq:3.9 wait for it to come up and run from a second shell podman exec -it -u rabbitmq $HOST rabbitmqctl enable_feature_flag all (or run /bin/bash and check with rabbitmqctl list_feature_flags rabbitmqctl enable_feature_flag all rabbitmqctl list_feature_flags ) after doing this three times with 3.9 3.10 and 3.11 restart services epmd and then rabbitmq-server , and things should work now. Once happy, you can remove the podman images. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2074309 Title: rabbitmq-server upgrade 22.04 -> 24.04 completely broken To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rabbitmq-server/+bug/2074309/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
