问题描述
安装 Google Chrome 会导致添加第三方软件源，可以从中检索 Google Chrome 升级：
$ cat /etc/apt/sources.list.d/google-chrome.list
### THIS FILE IS AUTOMATICALLY CONFIGURED ###

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

如何从此存储库启用无人值守升级？
最佳方法
-
安装无人值守升级：
sudo apt-get install unattended-upgrades -
通过编辑无人值守升级列表并在其中添加 Google Chrome 存储库，在 Google Chrome 存储库上启用无人值守更新：
sudo gedit /etc/apt/apt.conf.d/50unattended-upgrades将
"Google\, Inc.:stable";添加到允许的来源：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 LLC:stable"; }; -
测试 使用
sudo unattended-upgrade --dry-run进行测试，如果一切顺利，您应该安装了 Google Chrome 的更新，而无需您的任何干预。
要检查它是否在空运行后跟踪日志：
cat /var/log/unattended-upgrades/unattended-upgrades.log
您应该在日志中看到与此类似的内容：
2011-10-11 18:03:23,292 INFO Allowed origins are: [‘o=Ubuntu,a=oneiric-security’, ‘o=Google, Inc.,a=stable’]
您可以通过编辑文件 /etc/apt/apt.conf.d/10periodic 来更改无人值守更新的配置，配置选项在 /etc/cron.daily/apt 脚本头中。阅读它们以配置无人值守更新的频率。
