apt sources.list中的文件扩展名无效

N: Ignoring file 'yandex-browser.list.save.1' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension N: Ignoring file 'yandex-browser.list.save.2' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension E: Type 'andex.ru/yandex-browser/deb' is not known on line 1 in source list /etc/apt/sources.list.d/yandex-browser.list E: The list of sources could not be read. 

我怎样才能解决这个问题？

Answer 1

在终端运行

 sudo rm /etc/apt/sources.list.d/yandex-browser* 

问题应该解决。

某些脚本或您在安装Yandex浏览器时损坏了一些sources.list文件。
