Apt update issue

[FMotalleb]

This issue happened on my Ubuntu nobel servers
the fix is straightforward: adding signed-by=/etc/apt/keyrings/docker.asc to apt source file
Error:

Failed to update apt cache:
W:Updating from such a repository can't be done securely, and is therefore disabled by default.,
W:See apt-secure(8) manpage for repository creation and user configuration details.,
W:GPG error: http://nexus.local:8081/repository/docker-linux/ubuntu noble InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 7EA0A9C3F273FCD8,
E:The repository 'http://nexus.local:8081/repository/docker-linux/ubuntu noble InRelease' is not signed.

Fix:

# in vars
docker_apt_repository: "deb [arch={{ docker_apt_arch }}{{' signed-by=/etc/apt/keyrings/docker.asc' if add_repository_key is not failed}}] {{ docker_repo_url }}/{{ ansible_distribution | lower }} {{ ansible_distribution_release }} {{ docker_apt_release_channel }}"
