Hi Luc,

The easiest way is to just specify the version you want in the ansible apt command like this:

- name: Install the version '1.00' of package "foo"

apt:

name: foo=1.00

Although for “yum” you’ll need to replace the “=” with a “-“ .. So it will be something like:

- name: Install one specific version of Apache
 yum:
 name: httpd-2.2.29-1.4.amzn1
 state: present

You’ll have to find the version numbers etc for the packages you want.

Hope this helps.

Simon.

Dear Simon,

Thank you for your answer.

Yes the update is probably the mistake.
Can you please tell me how to pin the version in my playbook ?

Best regards,
Luc

Hi Luc,

Erlang and Rabbit have a very “interesting” relationship. Different versions of RabbitMQ are very dependent on a particular version of Erlang. I have to pin the versions to be installed in my playbooks as the defaults don’t always work.

The table where you can look-up the versions required is at:

https://www.rabbitmq.com/which-erlang.html

There was a new version of Erlang released on the 12th May so this may be what is hampering you.

Cheers,

Simon.

Dear all,

I have a strange error with rabbitmq on ubuntu 20.04. The playbook was working previously on this OS but now I have this error:

Does anyone have any idea how to solve this ?
