无法在发布文件中找到预期的条目’restricted / binary-amd64 / Packages’

我使用64位Ubuntu 14.04。 当我运行sudo apt-get update它会出现以下错误。

 Unable to find expected entry 'restricted/binary-amd64/Packages' in Release file W: Failed to fetch http://archive.ubuntukylin.com:10006/ubuntukylin/dists/trusty/Release Unable to find expected entry 'restricted/binary-amd64/Packages' in Release file (Wrong sources.list entry or malformed file) E: Some index files failed to download. They have been ignored, or old ones used instead. 

谁能告诉我如何解决这个问题?

打开终端并执行以下命令行(重置存储库):

 sudo echo "deb http://archive.ubuntu.com/ubuntu trusty main universe restricted multiverse" > /etc/apt/sources.list 

然后执行:
sudo apt-get update

现在它应该修复。
