无人值守升级失败

Question

我在 apt-get upgrade 上不断收到此错误：

Installing unattended-upgrades (0.93.1+nmu1) ...
Failed to start unattended-upgrades.service: Unit unattended-upgrades.service failed to load: Invalid argument. See system logs and 'systemctl status unattended-upgrades.service' for details.

我不关心无人值守的升级，它可以被删除。我试过 apt-get remove 但没有运气：

Removing unattended-upgrades (0.93.1+nmu1) ...
Failed to stop unattended-upgrades.service: Unit unattended-upgrades.service not loaded.
invoke-rc.d: initscript unattended-upgrades, action "stop" failed.
dpkg: error processing package unattended-upgrades (--remove):

这些信息已被翻译，因为其中一些不是英文的。

我已经配置了 sid 存储库的 debian jessie。

用户名 -a: Linux PRODUCTION 3.16.0-4-amd64 #1 SMP Debian 3.16.43-2 (2017-04-30) x86_64 GNU/Linux

猫 /etc/debian_version: 9.0

我只是想让那个讨厌的错误消失，我不在乎如何。通过删除软件包或修复问题，但我似乎无法删除它，也由于缺乏知识而无法修复它:)

任何提示？

Answer 1

systemctl mask unattended-upgrades

解释：

systemd 单元可以被管理员覆盖，在/etc/systemd/system.

此机制还可用于“屏蔽”服务被套接字激活、手动启动或任何其他方法激活。如果有指向 的符号链接/dev/null，而不是创建同名文件，则该单元将被有效地忽略。

所以你可以 ab(use) systemctl mask，用空替换单元的内容。

为避免将来可能出现的混淆，请在取下包装后检查是否取下面罩。 systemctl unmask unattended-upgrades.
