Почему не работает utorrent? Как мне решить эту проблему?

Я попытался установить utorrent, следуя инструкциям, доступным по адресу http://www.liberiangeek.net/2012/01/install-utorrent-in-ubuntu-11-10-oneiric-ocelot/, но когда я добрался до шаг ввода:

utserver -settingspath /opt/utorrent-server-v3_0/

в терминал I получил выход:

, а затем после дня его застревания в этот момент он все еще не установил utorrent сервер.

Я использую 12.10 i386 на ноутбуке Dell Vostro 3500, если требуется дополнительная информация.
