我是 Linux 平台的新手。请在完整阅读之前不要将此问题标记为重复。！
我的系统在处理器上运行intel i5，我最近安装的操作系统是64-bit Ubuntu 13.10。我必须安装一组库才能使我的 android 开发工具 ( ADT) 正常运行。一切都从我的系统和开发环境的 linux 化开始！
这是链接我为此提起了诉讼。
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install ia32-libs
我还使用了加速 Ubuntu 13.10 的技巧
但是，每当我执行时 sudo apt-get update，它都会多次重复显示以下警告信息。

我尝试使用此论坛中要求编辑文件的各种答案来解决问题。但我的 sources.list 文件中sources.list没有这些内容 ( )。binary-i686 or binary-i586
有人能帮我解决这个问题吗？请不要忘记用命令回答，因为我对此知之甚少linux terminal commands！！
答案1
打开sources.list文件，
sudo gedit /etc/apt/sources.list
删除上面提到的行。然后保存文件。
对于导致错误的 PPA，您还必须从/etc/apt/sources.list.d目录中删除该 PPA 文件。
之后运行以下命令更新存储库：
sudo apt-get update
