RabbitMQ Upgrade from 3.8.2 to 3.8.6 on Debian -- How to Install Latest Version?

I'm trying to upgrade RabbitMQ on a cluster of two Linux VMs created via Bitnami in Azure (running Debian 9 Stretch) from version 3.8.2 to the newest version, 3.8.6. According to RabbitMQ's documentation, I can do a rolling upgrade by stopping one of the nodes, installing the newest version on it, restarting that node, and then doing the same on the other node. The machines are running with Erlang 22, which RabbitMQ states is compatible with the 3.8.6 release:

bitnami@AI-RabbitMQ-02:~$  erl -eval 'erlang:display(erlang:system_info(otp_release)), halt().'  -noshell
"22"

Following the documentation steps for installation using PackageCloud, I've installed the repository successfully, with this output:

bitnami@AI-RabbitMQ-02:~$ sudo rabbitmqctl stop_app

bitnami@AI-RabbitMQ-02:~$ curl -s https://packagecloud.io/install/repositories/rabbitmq/rabbitmq-server/script.deb.sh | sudo bash                                                                                                          abbitmq/rabbitmq-server/script.deb.sh | sudo bash

The repository is setup! You can now install packages.

Then, I try the next step, to install RabbitMQ, being presented with the following errors:

bitnami@AI-RabbitMQ-02:~$ sudo apt-get install rabbitmq-server=3.8.6-1

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

E: Unable to correct problems, you have held broken packages.

I've attempted to do the install with the Bintray option as well, but to no avail. I've tried installing manually with dpkg -i as well, but I'm not sure how to handle the package dependencies, since the link on Rabbit's page for that step doesn't lead anywhere. Any help with the upgrade would be greatly appreciated. Thank you very much!

I had Erlang 23 and RabbitMQ Server 3.8.2 (they are not fully compatible so I decided to upgrade RabbitMQ Server to 3.8.9 because I had some problems running my app)

I have a cluster with one node on AWS EC2 instance of Ubuntu 20.04 (unconfigured yet properly as RabbitMQ advises via plugin - I plan to do it later).

What I did and it worked for me (following commands executed under sudo or root sudo su):

  1. It's important to shutdown not just stop_app as Erlang also needs to be stopped and stop_app only stops RabbitMQ Server leaving Erlang on which would later might give you error while starting new version of the RabbitMQ Server - for port 25672 being busy with another app:

    rabbitmqctl shutdown

  2. Change in rabbitmq file from old version (I had for some strange reason 3.8.8 instead of 3.8.2 which I run) to a new one - in my case 3.8.9:

    vim /etc/apt/preferences.d/rabbitmq

  3. Recheck if dependencies are installed:

    apt-get -y install socat logrotate init-system-helpers adduser

  4. Install wget if you don't have it:

    apt-get -y install wget

  5. Download latest .deb package of server installation file:

    wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.9/rabbitmq-server_3.8.9-1_all.deb

  6. Install it:

    dpkg -i rabbitmq-server_3.8.9-1_all.deb

  7. Remove distro:

    rm rabbitmq-server_3.8.9-1_all.deb

  8. Check if server stopped (may be redundant command):

    service rabbitmq-server stop

  9. Restart server:

    service rabbitmq-server restart

  10. Check server status:

    rabbitmq-server status

  11. If it gives you an error BOOT FAILED. Distribution port 25672 is in use by another node, check who uses that port it may be that Erlang uses that port:

    lsof -i :25672

  12. Start RabbitMQ app:

    rabbitmqctl start_app

  13. Check status of node:

    rabbitmqctl status

You should see upgraded RabbitMQ Server version (in my case 3.8.9) along with you recent Erlang version (in my case 23)
