Ошибка инструмента сборки Scala в Ubuntu [дубликат]

Я установил Apache Spark (1.5.2) и записную книжку IPython (0.12.1) в моем Ubuntu 12.04. Перед созданием профиля для IPython специально для PySpark я хочу установить инструмент сборки scala. Я выполнил следующий запрос, чтобы создать sbt.

wget http://apt.typesafe.com/repo-deb-build-0002.deb `

#Install the repository
sudo dpkg -i repo-deb-build-0002.deb

#Refresh
sudo apt-get update

При запуске apt-get update я получил указанную ниже ошибку.

user@user-VirtualBox:~/spark$ sudo apt-get update
E: Malformed line 2 in source list /etc/apt/sources.list.d/sbt.list (dist)
E: The list of sources could not be read.

Я поискал в Интернете, чтобы решить эту проблему. В соответствии с инструкциями в сети проблема находится в строке 2, я прокомментировал строку 2, т.е.

# deb http://in.archive.ubuntu.com/ubuntu/ precise main restricted
deb-src http://in.archive.ubuntu.com/ubuntu/ precise main restricted

Ниже приведен фактический результат /etc/apt/sources.list

$ cat /etc/apt/sources.list

После комментариев я все еще получение неверной строки 2 в списке источников /etc/apt/sources.list.d/sbt.list ошибка.

Как я могу решить эту проблему? Поскольку мне нужно решить эту проблему и создать профиль в IPython.
