要执行此操作，请运行以下命令(按Ctrl+Alt+T打开终端)：
sudo -H gedit /etc/apt/sources.list
如有必要，用另一个文件名替换/etc/apt/sources.list。
查找格式不正确的行(参考错误的行号)，以下是正确格式化行的示例：
# Comment, marked by a line starting with '#'
deb http://site.example.com/debian distribution component1 component2 component3
deb-src http://site.example.com/debian distribution component1 component2 component3
保存文件，并退出文本编辑器，然后，在终端窗口中运行此命令：
sudo apt-get update
假设没有错误，问题就解决了，你应该能够运行软件中心。

快速方法
这个问题的解决方法是从头构建sources.list条目。
deb http://archive.ubuntu.com/ubuntu precise main universe restricted multiverse
deb-src http://archive.ubuntu.com/ubuntu precise universe main multiverse restricted
deb http://security.ubuntu.com/ubuntu/ precise-security universe main multiverse restricted
deb http://archive.ubuntu.com/ubuntu precise-updates universe main multiverse restricted
deb http://archive.ubuntu.com/ubuntu precise-backports universe main multiverse restricted
# deb http://archive.canonical.com/ubuntu precise partner
# deb-src http://archive.canonical.com/ubuntu precise partner
# deb http://extras.ubuntu.com/ubuntu precise main
# deb-src http://extras.ubuntu.com/ubuntu precise main
复制上面的内容，并用root权限打开sources.list文件。
sudo -H gedit /etc/apt/sources.list 这在终端和按回车键将做这项工作。
然后保存，并关闭gedit。
然后执行sudo apt-get update，你将看到存储库列表已更新。
