我正在尝试使用rvm安装ruby，但由于apt-get update问题而失败。我发现这是由etc / apt目录中的sources.list文件出现问题引起的。我尝试使用此http://blog.ubuntu-tweak.com/guide/how-to-fix-the-source-list-files来理解和修复我的源文件。当我从sources.list删除“坏线”时，没有留下任何行。此时我能够成功地进行apt-get更新，但是rvm install ruby仍然失败，因为它现在无法找到必要的依赖项。我开始考虑全新安装，因为我不知道还能做什么，但我想我先在这里寻求帮助。

E: Some index files failed to download. They have been ignored, or old ones used instead.
答案 0 :(得分：8)
您好像正在使用Ubuntu 13.04（Raring Ringtail），自2014年1月27日起不再支持。
如果您还不想更新，还可以在archive.ubuntu.com文件中用security.ubuntu.com替换old-releases.ubuntu.com和sources.list（可能只是使用脚本我wrote自动执行相同的操作）
[更新]为@ wes-johnson在评论中说明，我删除了dist-upgrade，因为它将使用旧源并且无论如何都不起作用。
