RabbitMQ not starting with message "init terminating in do_boot, noproc" on Ubuntu 18.04 - rabbitmq

Question

I cannot seem to start or install my RabbitMQ server anymore for my Ubuntu 18.04 anymore. I tried to remove and install it again, but it cannot finish the install because configuration fails. When I try to run sudo apt-get install --fix-broken. This is the result of it failing:

Then when checking the log files they doesn't provide much more information either. Here is startup_err log file content:

And here is startup_log file content:

The other log files it claim to use for logging are empty. For example log file rabbit#ubuntu-dev.log and rabbit#ubuntu-dev-sasl.log.
I also found this post, which explains to check your hostname in /etc/hostname file but I checked and it's correct.
kazhu#ubuntu-dev:/var/log/rabbitmq$ cat /etc/hostname
ubuntu-dev
I also checked RabbitMQ troubleshoot guide and they said to check log folder permissions and they are right to my eye:
kazhu#ubuntu-dev:/var/log/rabbitmq$ ll

Guide also stated that perl chrash dump file contains detailed information of the problem and requires Erlang expertises, which I don't have. So decided to upload the file to my Dropbox for you to see.
Can somebody help me solve this? I've tried some time myself but gave up because cannot figure out what the problem seems to be :/

Answer 1

I solved the problem with help of my colleague. I had installed newest erlang and rabbitmq from outside apt source separately. Now when I removed and purged everything related to rabbitmq and erlang, and removed the added apt sources too. Then I just ran sudo apt install rabbitmq-server and it wanted to install erlang packages too because of the dependency. And it installed and everything is working fine after that.
Wanted to share this solution if somebody else has the same problem as me.
UPDATE 9.12.2020:
Someone asked how I removed RabbitMQ and Erlang. I don't fully remember but I think I was following this guide: https://www.rabbitmq.com/install-debian.html.
The point is to remove the installed RabbitMQ and Erlang packages from added repositories and their configuration with
sudo apt purge rabbitmq-server erlang
You might need to search for rest of the erlang packages with
apt list | grep erlang
Then you need to remove added apt repositories. Usually added repositories in Ubuntu goes under /etc/apt/sources.list.d/ folder. Look for files names like rabbitmq and erlang. Make sure you are not deleting any other files!
After this run sudo apt update and apt should remove removed apt repositories. Then just running sudo apt install rabbitmq-server should do the trick and install Erlang package as a dependence. Of course installing this way you get much older version than using added repositories.
