（2）原因+解决：
①没有安装Chrome，安装：
#将下载源加入到系统的源列表
sudo wget http://www.linuxidc.com/files/repo/google-chrome.list -P /etc/apt/sources.list.d/
#导入谷歌软件的公钥，用于下面步骤中对下载软件进行验证
wget -q -O - https://dl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
#对当前系统的可用更新列表进行更新
sudo apt-get update
这里执行报错，解决 sudo gedit /etc/apt/sources.list.d/google-chrome.list 删掉
https://repo.fdzh.org/chrome/deb stable InRelease即可
：

#执行对谷歌 Chrome 浏览器（稳定版）的安装
sudo apt-get install google-chrome-stable
②此处安装时用的普通用户，root用户无法打开。需要修改配置。
#查看浏览器位置
$ whereis google-chrome
#修改浏览器
$ sudo gedit /usr/bin/google-chrome
#将该文件中 exec -a "$0" "$HERE/chrome" "$@" 改为：
exec -a
