Error in crowdsec installation

[DavidGL17]

(installing on an Ubuntu server 20.04) Hey, i am trying to adapt your playbook to my usage and during my exploration of every role, found an error during the installation of crowdsec.

- name: Add Crowdsec GPG apt Key
  apt_key:
    url: https://packagecloud.io/crowdsec/crowdsec/gpgkey
    state: present
https://docs.github.com/github/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax
- name: Add Crowdsec Repository
  apt_repository:
    repo: deb https://packagecloud.io/crowdsec/crowdsec/ubuntu bionic stable
    state: present

These two tasks do not allow for crowdsec to be installed with apt (with the next task in the file). I tried a bit on my side, and found this workaround :

- name: add Crowdsec repo and gpg apt key
  shell:
    cmd: curl -s https://packagecloud.io/install/repositories/crowdsec/crowdsec/script.deb.sh | sudo bash

This task fixes the issue and allows to install crowdsec.

(BTW, ty very much for this repository and your videos, you have given me a nice objective to work for as i try to create my own private server. Hope this will help!)

What is the error?

Using shell is not the best idea, since Ansible has specialized modules for adding repositories and installing packages

when trying to install the package with apt it does not find it in the available packages.

I ran into a similar issue using the role as reference. Here's an example of the exact error.

TASK [system : Install CrowdSec and iptables bouncer] ************************************************************************************************
fatal: [myhost]: FAILED! => {"changed": false, "msg": "No package matching 'crowdsec' is available"}

When running apt update on the host, I would get these warnings too.

W: Skipping acquire of configured file 'stable/binary-amd64/Packages' as repository 'https://packagecloud.io/crowdsec/crowdsec/ubuntu focal InRelease' doesn't have the component 'stable' (component misspelt in sources.list?)

I understand we need to use 'main' instead of 'stable', I was able to resolve my issue with the following task definition for adding the apt repository.

- name: Add CrowdSec apt repository
    apt_repository:
      repo: deb https://packagecloud.io/crowdsec/crowdsec/{{ansible_lsb['id']|lower}} {{ansible_lsb['codename']}} main
      state: present

@DavidGL17 @dannycjones Please re-test with the latest version

If I switch from 'stable' component to 'main' component, issue goes away and installation is successful.

- name: Add CrowdSec apt repository
    apt_repository:
      repo: deb [arch=amd64] https://packagecloud.io/crowdsec/crowdsec/ubuntu focal main
      state: present

In the CrowdSec deb installation guide, they are using 'main' component.
