}

Esto ocurre porque:

• Ansible 2.16.3 no es totalmente compatible con Python 3.12.

• Ubuntu 24.04 bloquea la instalación global de paquetes Python (externally-managed-environment).

🛠 Causas del Error

✅ Soluciones Definitivas

Usar Python 3.11 (Recomendado), en el Host Remoto:

# Instalar Python 3.11 desde deadsnakes PPA
sudo add-apt-repository ppa:deadsnakes/ppa -y
sudo apt update
sudo apt install -y python3.11 python3.11-venv

# Configurar como alternativa predeterminada
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.11 1
sudo update-alternatives --set python3 /usr/bin/python3.11

# Instalar dependencias
python3 -m pip install ansible-core==2.16.3 six

Y acá la prueba de que funciona bien ahora.

ansible all -m ping -i inventory.ini
