我在更新源方面遇到了一点问题,我正在运行的是Ubuntu Natty Narwhal系统,而且我正在尝试使用二进制文件安装一个名为Fire Sheep的Firefox插件。不知怎么回事,我的更新源被改动了,每次我尝试更新时都会出现这个错误信息。
An unresolvable problem occurred while initializing the package information.
Please report this bug against the 'update-manager' package and include the following error message:
'E:Type 'See' is not known on line 2 in source list /etc/apt/sources.list'
/etc/apt/sources.list
的第二行无效。请您能提供该行的内容吗? - Florian Diesch
