How to fix error while installing RabbitMQ ubuntu 18?

Question

ubuntu

Installed RabbitMQ as follows:

echo "deb http://www.rabbitmq.com/debian/ testing main"  | sudo tee  /etc/apt/sources.list.d/rabbitmq.list > /dev/null
wget https://www.rabbitmq.com/rabbitmq-signing-key-public.asc
sudo apt-key add rabbitmq-signing-key-public.asc
sudo apt-get update
sudo apt-get install rabbitmq-server

But during installation it gives an error:

log

I found on the forums that I just need to change /etc/hosts and /etc/hostname, but it’s not clear how and what to change there

In my opinion, adding the debian testing repository to Ubuntu was a mistake. Most likely package dependencies were broken.
It's easier to remove this repository and install the stock version of RabbitMQ included in the Ubuntu repository.
