当我检查更新时，出现“无法下载存储库信息”错误。
这是详细信息下的内容：
W: Failed to fetch gzip:/var/lib/apt/lists/partial/us.archive.ubuntu.com_ubuntu_dists_natty_main_source_Sources Hash Sum mismatch,
E: Some index files failed to download. They have been ignored, or old ones used instead.
我使用的是 Google Chrome 48.0 32 位。今天当我启动谷歌浏览器时，我收到了这条消息：
This computer will soon stop receiving Google Chrome updates because
this Linux system will no longer be supported
我认为 Ubuntu 14.04 支持五年，这里到底发生了什么？
在 64 位 Ubuntu 上，我从更新管理器收到错误消息apt-get update：
Failed to fetch http://dl.google.com/linux/chrome/deb/dists/stable/Release
Unable to find expected entry 'main/binary-i386/Packages' in Release file
(Wrong sources.list entry or malformed file)
Some index files failed to download.
They have been ignored, or old ones used instead.
