因为官方的Google Chrome库不再提供32位包
修改文件内容

sudo gedit /etc/apt/sources.list.d/google-chrome.list

原来是

deb http://dl.google.com/linux/chrome/deb/ stable main

改为：

deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main

逐层新建 /opt/google/chrome/cron
打开文件

sudo gedit /opt/google/chrome/cron/google-chrome

写入相同内容
如果本来就已经存在该文件，就输入

sudo sed -i -e 's/deb http/deb [arch=amd64] http/' "/opt/google/chrome/cron/google-chrome"
