apt-get 更新失败 ubuntu 14.04

Question

我正在尝试做

sudo apt-get update

但我收到以下错误：

W: Failed to fetch http://ftp.udc.es/ubuntu/dists/trusty/Release  Unable to find   expected entry 'main/binary-x8-64/Packages' in Release file (Wrong sources.list entry or malformed file)

我已经尝试重置 /etc/apt/sources.list 就像这里建议的那样：

如何恢复默认存储库？

并且还尝试选择另一台服务器来下载更新：Ubuntu 12.04 上的“sudo apt-get update”错误

但我一直收到同样该死的错误信息。有任何想法吗？

正如评论中所问，做：

$ grep -R ftp.udc.es /etc/apt/sources.list*
/etc/apt/sources.list:deb http://ftp.udc.es/ubuntu/ trusty main universe
/etc/apt/sources.list.save:deb http://ftp.udc.es/ubuntu/ trusty main

$ cat sources.list
## See sources.list(5) for more information, especialy
# Remember that you can only use http, ftp or file URIs
deb http://ftp.udc.es/ubuntu/ trusty main universe
# CDROMs are managed through the apt-cdrom tool.

$ dpkg --print-architecture 
amd64
$ dpkg --print-foreign-architectures
i386 
x8664
x8-64
x864

Answer 1

从 的输出中可以看出dpkg --print-foreign-architectures，出于某种原因，您添加了一堆无效的架构。删除它们：

sudo dpkg --remove-architecture x8664
sudo dpkg --remove-architecture x8-64
sudo dpkg --remove-architecture x864

将来，请检查您要添加的内容。
