Instale ODOO con los scripts que figuran en el foro install_1.sh e install_2.sh   en principio funcionó todo. Faltaba install con pip install pyafipws 

configure el certificado de afip.. en Punto de venta aprieto el boton GET CONNECTION y todo OK.. el DUMMY TEST y da todo ok.. pero el resto da el siguiente error.. ya probe desinstalar e instalar como 5 veces.. jeje

si alguien pudiera darme una mano se agradecerá!
