The Ansible module install_apt_key_and_repo allows for easy installation of an APT key and addition of an APT repository on a target host. This was tested and created on Ubuntu 22 with and for the repository of PostgreSQL. If it works on other repositories thats nice, if not it may or may not be added in future. You are welcome to extend the module and make pull requests.

• A supported operating system using APT (Advanced Package Tool).

• key_url: URL of the APT key to be imported. Required.
• repo_url: URL of the APT repository to be added. Required.
• distribution_codename: The distribution's codename (e.g., jammy, buster). Required.
• repo_name: The name of the repository to be added. Required.

distributions_codename can be found by running lsb_release -c on the target host. It is together with the repo_name needed on the one hand to create the file in /etc/apt/sources.list.d/ that contains the repository and on the other hand to make the right command e.g. f"sudo sh -c 'echo \"deb {repo_url} {codename}-{repo_name} main\" > /etc/apt/sources.list.d/{repo_name}.list'"
