安裝 Google Chrome 會導致新增第三方軟體來源，可以從中擷取 Google Chrome 升級：
$ cat /etc/apt/sources.list.d/google-chrome.list
### THIS FILE IS AUTOMATICALLY CONFIGURED ###

如何從此儲存庫啟用無人值守升級？
答案1
安裝無人升級：
sudo apt-get install unattended-upgrades透過編輯無人值守升級清單並在其中新增 Google Chrome 儲存庫，在 Google Chrome 儲存庫上啟用無人值守更新：
sudo gedit /etc/apt/apt.conf.d/50unattended-upgrades添加
"Google LLC:stable";到允許的來源：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"; };測試
用於
sudo unattended-upgrade --dry-run測試，如果一切順利，您應該在沒有任何干預的情況下安裝 Google Chrome 的更新。
要在空運行後檢查日誌是否正常運作：
cat /var/log/unattended-upgrades/unattended-upgrades.log
你應該在日誌中看到類似這樣的內容：
2011-10-11 18:03:23,292 INFO 允許的來源是： ['o=Ubuntu,a=oneiric-security', 'o=Google, Inc.,a=stable']
您可以透過編輯檔案來變更無人值守更新的配置/etc/apt/apt.conf.d/10periodic，而配置選項位於/etc/cron.daily/apt腳本標題中。閱讀它們以配置無人值守更新的頻率。
答案2
編輯/etc/apt/apt.conf.d/50unattended-upgrades並在其中添加一行Origins-Pattern：
Unattended-Upgrade::Origins-Pattern {
// Keep existing content here, just add:
"origin=Google LLC,codename=stable";
}
