Ошибка при установке openstack на ubuntu 15.10 с использованием devstack

Я установил VMware player 12. Но выполняя эту команду ./stack.sh для установки openstack, я получаю сообщение об ошибке ./stack.sh: line 623: /home/aryan/devstack/.localrc.password: Permission denied

Любая помощь? Вот полное сообщение:
