в выводе команды видно ошибку The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 7EA0A9C3F273FCD8
Исправить данную проблему можно следующим образом, следуя инструкции с официальном сайта docker https://docs.docker.com/engine/install/ubuntu/ . Нам нужен пункт Set up the repository
Add Docker’s official GPG key:
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
Use the following command to set up the repository:
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
теперь ключ добавлен и можно выполнять команду ansible-playbook install_iot.yml
