Ansible: Importing GPG-keys from RPM Fusion not working

Question

I'm trying to create a task to download and import the GPG-keys from the official RPM Fusion site but it fails.

- hosts: localhost
  connection: local
  name: DOWNLOADING AND IMPORTING SECURITY KEYS
  tasks:
    - name: Downloading the security key for RPM Fusion (free) repo
      get_url:
        url: https://rpmfusion.org/keys?action=AttachFile&do=get&target=RPM-GPG-KEY-rpmfusion-free-fedora-2020
        dest: ~/Downloads/free_keys.txt

    - name: Importing (free) key
      ansible.builtin.rpm_key:
        state: present
        key: ~/Downloads/free_keys.txt

    - name: Deleting security key file (free)
      ansible.builtin.file:
        path: ~/Downloads/free_keys.txt
        state: absent

    - name: Downloading the security key for RPM Fusion (non-free) repo
      get_url:
        url: https://rpmfusion.org/keys?action=AttachFile&do=get&target=RPM-GPG-KEY-rpmfusion-nonfree-fedora-2020
        dest: ~/Downloads/nonfree_keys.txt

    - name: Importing (non-free) key
      ansible.builtin.rpm_key:
        state: present
        key: ~/Downloads/nonfree_keys.txt

    - name: Deleting security key file (non-free)
      ansible.builtin.file:
        path: ~/Downloads/nonfree_keys.txt
        state: absent

This is the output:

So far I've tried to download the keys to .txt and .gpg format but none of these methods work. Any suggestion is greatly appreciated.

2. The keys are the ones under 'Fedora 34' in this link.
3. Yes, the keys downloaded look like that.
4. Unfortunately, changing the permissions did not work.

Looks like a solution could be to download the distribution-gpg-keys from the official repos before installing the RPM Fusion.

Answer 1

After some digging I found the solution and it's simpler than I thought:

---
- hosts: localhost
  connection: local
  name: IMPORTING SECURITY KEYS
  tasks:
    - name: Importing (free) key
      ansible.builtin.rpm_key:
        state: present
        key: https://rpmfusion.org/keys?action=AttachFile&do=get&target=RPM-GPG-KEY-rpmfusion-free-fedora-2020

    - name: Importing (non-free) key
      ansible.builtin.rpm_key:
        state: present
        key: https://rpmfusion.org/keys?action=AttachFile&do=get&target=RPM-GPG-KEY-rpmfusion-nonfree-fedora-2020

Following the official documentation, I thought you had to download the keys to your PC and then install them. Instead, you can directly enter the URL into the key section.
