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.
