“неожиданное пустое сетевое имя” в backuppc на Ubuntu 14.04

Я пытаюсь установить backuppc на Ubuntu 14.04. Я пытался сделать это после этого Цифрового Океанского учебного руководства и также этого на dalaris.com, но это дает мне сообщение об ошибке, когда я добавляю Windows PC и попытку выполнить его впервые.

unexpected empty share name

Я получил это сообщение теперь
