無人值守升級無法自行更新：收到 SIGUSR1，將停止

我們在 ubuntu xenial 上使用“無人值守升級”。

由於幾天“uu”無法自我更新：

手動執行：unattended-upgrades -d

消息：

...pkg 'powermgmt-base' not in allowed origin...

我的出身：

"${distro_id}:${distro_codename}-security";
"${distro_id}:${distro_codename}-updates";

編輯：

我找到了正確的來源：

"${distro_id}:${distro_codename}";

現在的問題是，“UU”無法自我更新：

Preparing to unpack .../unattended-upgrades_1.1ubuntu1.18.04.7~16.04.3_all.deb ...
SIGUSR1 received, will stop
SIGUSR1 received, will stop
SIGUSR1 received, will stop
SIGUSR1 received, will stop

有什麼建議嗎？

在/etc/apt/apt.conf.d/50unattended-upgrades中，將以下設置更改為false：

// Split the upgrade into the smallest possible chunks so that
// they can be interrupted with SIGUSR1. This makes the upgrade
// a bit slower but it has the benefit that shutdown while a upgrade
// is running is possible (with a small delay)
Unattended-Upgrade::MinimalSteps "true";

這為我解決了這個問題：Unattended-Upgrade::MinimalSteps “false”;

這是以前的“真實”！
