源列表第 3 行中类型 '' 未知

Question

当我输入时sudo apt-get update，出现此错误：

$ sudo apt-get update
N: Ignoring file 'getdeb.list.bck' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
E: Type '' is not known on line 3 in source list /etc/apt/sources.list.d/libdvdcss.list
E: The list of sources could not be read.

Answer 1

将文件移动getdeb.list.bck至另一位置。

sudo mv /etc/apt/sources.list.d/getdeb.list.bck ~/Desktop

然后''从文件/etc/apt/sources.list.d/libdvdcss.list第 3 行中删除。

您可以通过sudo -H nautilus命令执行此操作。最后运行sudo apt-get update以更新所有存储库。
