我在 Ubuntu 12.04 中安装了 Apache spark(1.5.2) 和 IPython(0.12.1) 笔记本。在为 PySpark 专门创建 IPython 配置文件之前，我想安装 scala 构建工具。我按照以下查询来构建 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
运行 apt-get update 时出现以下错误。
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.
我在网上搜索了这个问题的解决办法。根据网上的说明，问题出在第 2 行，我注释了第 2 行，即
# deb http://in.archive.ubuntu.com/ubuntu/ precise main restricted
deb-src http://in.archive.ubuntu.com/ubuntu/ precise main restricted
以下是实际输出/etc/apt/sources.list
$ cat /etc/apt/sources.list

评论后，我仍然收到源列表中第 2 行格式错误/etc/apt/sources.list.d/sbt.list错误。
我该如何解决这个问题？因为我需要解决这个问题，并且需要在 IPython 中创建配置文件。
答案1
它抱怨文件中第 2 行格式不正确/etc/apt/sources.list.d/sbt.list，而不是 /etc/apt/source.list 文件。
您可以尝试做同样的事情来注释掉第二行（或用正确的格式修复它）/etc/apt/sources.list.d/sbt.list文件。
