Как решить & ldquo; сбой команды release & rdquo; в быстром приложении Hello-World?

Я новичок в Ubuntu и новичок в программировании. Я смотрел видео на http://developer.ubuntu.com/get-started/ , и видео сделало его таким простым. Я следовал всем шагам, и все шло хорошо, пока я не попытался выпустить приложение, как показано в видео.

Я уверен, что я не единственный, кто получил эту ошибку. Подскажите пожалуйста, как исправить ошибку.

Вот ошибка, которую я получил. (Я удалил свое имя и адрес электронной почты из сообщения об ошибке.)
