安装 Google Chrome 会添加第三方软件源，可以从中检索 Google Chrome 升级：
$ cat /etc/apt/sources.list.d/google-chrome.list

如何从该存储库启用无人值守升级？
答案1
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添加
"Google LLC: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 LLC:stable"; };测试
用来
sudo unattended-upgrade --dry-run测试，如果一切顺利，您应该无需任何干预即可安装 Google Chrome 更新。
要检查其是否正常工作，请在空运行后跟踪日志：
cat /var/log/unattended-upgrades/unattended-upgrades.log
你应该在日志中看到类似这样的内容：
2011-10-11 18:03:23,292 INFO 允许的来源为：['o=Ubuntu,a=oneiric-security', 'o=Google, Inc.,a=stable']
您可以通过编辑文件来更改无人值守更新的配置/etc/apt/apt.conf.d/10periodic，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。
答案2
编辑/etc/apt/apt.conf.d/50unattended-upgrades并在里面添加一行Origins-Pattern：
Unattended-Upgrade::Origins-Pattern {
// Keep existing content here, just add:
"origin=Google LLC,codename=stable";
}
