如何启用Google Chrome的无提示自动更新？

安装Google Chrome浏览器会导致添加第三方软件源，可从中获取Google Chrome升级：

$ cat /etc/apt/sources.list.d/google-chrome.list
### THIS FILE IS AUTOMATICALLY CONFIGURED ###
# You may comment out this entry, but any other modifications may be lost.
deb http://dl.google.com/linux/chrome/deb/ stable main

$ head -n 9 /var/lib/apt/lists/dl.google.com_linux_chrome_deb_dists_stable_Release
Origin: Google, Inc.
Label: Google
Suite: stable
Codename: stable
Version: 1.0
Date: Tue, 04 Oct 2011 00:57:43 +0000
Architectures: i386 amd64
Components: main
Description: Google chrome-linux repository.

$ grep '^Package: ' /var/lib/apt/lists/dl.google.com_linux_chrome_deb_dists_stable_main_binary-amd64_Packages 
Package: google-chrome-beta
Package: google-chrome-stable
Package: google-chrome-unstable

如何从该存储库启用无人值守升级？

1. 安装无人值守的升级：

   sudo apt-get install unattended-upgrades
   

2. 通过编辑无人参与的升级列表并在其中添加Google Chrome仓库，在Google Chrome仓库上启用无人参与的更新：

   gksudo gedit /etc/apt/apt.conf.d/50unattended-upgrades
   

   添加"Google\, Inc.:stable";到允许的来源：

   Unattended-Upgrade::Allowed-Origins {
       "${distro_id} ${distro_codename}-security";
   //  "${distro_id} ${distro_codename}-updates";
   //  "${distro_id} ${distro_codename}-proposed";
   //  "${distro_id} ${distro_codename}-backports";
    "Google\, Inc.:stable";
   };
   

3. 测试

   使用sudo unattended-upgrade --dry-run测试，如果都挺清楚的，你应该是具有更新，而不需要您进行任何干预安装谷歌浏览器。

要在空运行后检查日志是否正常运行，请执行以下操作：

cat /var/log/unattended-upgrades/unattended-upgrades.log

并且您应该在日志中看到与此类似的内容：

2011-10-11 18：03：23,292信息允许的来源是：['o = Ubuntu，a = oneiric-security'，'o = Google，Inc.，a = stable']

您可以通过编辑文件来更改无人参与更新/etc/apt/apt.conf.d/10periodic的配置，配置选项位于/etc/cron.daily/apt脚本头中。阅读它们以配置无人值守更新的频率。
