❌ failed to open browser: exit status 3

（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：

错误:5 https://repo.fdzh.org/chrome/deb stable InRelease

E: 仓库 “https://repo.fdzh.org/chrome/deb stable InRelease” 没有数字签名。
N: 无法安全地用该源进行更新，所以默认禁用该源。
N: 参见 apt-secure(8) 手册以了解仓库创建和用户配置方面的细节。

#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 "$0" "$HERE/chrome" "$@" --user-data-dir --no-sandbox
