無人值守升級忽略優先級

我似乎unattended-upgrades不遵循/etc/apt/preferences.

我正在維護一個 Debian 文件伺服器，其中設置了無人值守升級。rclone目前安裝了 from testing 的版本。使用aptrclone 更新時，會從測試中更新。但是，unattended-upgrades在測試儲存庫中執行更新時會被忽略。

無人值守升級是否會出現這種行為？我希望 rclone 跟隨更新測試儲存庫中的更新。輸出和系統設置的詳細資訊總結如下。

執行的輸出unattended-upgrade --dry-run --debug是：

Enabled logging to syslog via daemon facility
Initial blacklisted packages: 
Initial whitelisted packages:

pkgs that look like they should be upgraded:

fetch.run() result: 0
blacklist: []
whitelist: []
No packages found that can be upgraded unattended and no pending auto-removals

首選項文件/etc/apt/preferences是：

Package: *
Pin: release l=Debian-Security
Pin-Priority: 1000

Package: rclone
Pin: release a=testing
Pin-Priority: 950

Package: *
Pin: release a=stable
Pin-Priority: 900

Package: *
Pin: release a=stretch-backports
Pin-Priority: 800

Package: *
Pin: release a=testing
Pin-Priority: -1

該/etc/apt/sources.list文件是：

deb http://ftp.uk.debian.org/debian/ stretch main non-free contrib
deb-src http://ftp.uk.debian.org/debian/ stretch main non-free contrib

deb http://security.debian.org/debian-security stretch/updates main contrib non-free
deb-src http://security.debian.org/debian-security stretch/updates main contrib non-free

# stretch-updates, previously known as 'volatile'
deb http://ftp.uk.debian.org/debian/ stretch-updates main contrib non-free
deb-src http://ftp.uk.debian.org/debian/ stretch-updates main contrib non-free

# stretch-backports, previously on backports.debian.org
deb http://ftp.uk.debian.org/debian/ stretch-backports main contrib non-free
deb-src http://ftp.uk.debian.org/debian/ stretch-backports main contrib non-free

# testing 
deb http://ftp.uk.debian.org/debian/ testing main contrib non-free
deb-src http://ftp.uk.debian.org/debian/ testing main contrib non-free

中的origins/etc/apt/apt.conf.d/50unattended-upgrades配置如下：

Unattended-Upgrade::Origins-Pattern {
 "origin=${distro_id},codename=${distro_codename},archive=stable";
 "origin=${distro_id},codename=${distro_codename},archive=testing";
 "origin=${distro_id},codename=${distro_codename},label=Debian-Security";
 "origin=${distro_id} Backports,codename=${distro_codename}-backports,label=Debian Backports";
 "origin=Syncthing,archive=syncthing,codename=debian,label=Syncthing,component=stable";
 "origin=www.geogebra.net,codename=stable,component=main";
};

您需要為測試設置適當的代號：

Unattended-Upgrade::Origins-Pattern {
   "origin=${distro_id},codename=${distro_codename},archive=stable";
   "origin=${distro_id},codename=buster,archive=testing";
   "origin=${distro_id},codename=${distro_codename},label=Debian-Security";
   "origin=${distro_id} Backports,codename=${distro_codename}-backports,label=Debian Backports";
   "origin=Syncthing,archive=syncthing,codename=debian,label=Syncthing,component=stable";
   "origin=www.geogebra.net,codename=stable,component=main";

};
