我的一个 Raspberry Pi（运行 OSMC 的 Pi 2）出现更新错误。尝试执行手动 dist 升级失败，并在 apt 软件包本身上出现可疑错误：
Preconfiguring packages ...

进一步检查确认 apt 已损坏：

删除 APT（例如dpkg -r）进行重新安装并不是一个真正的选择，因为rbp2-设备-osmc依赖于取决于apt-utils，所以它会导致系统崩溃。
如何在不擦除整个安装的情况下恢复 apt？
答案1
跑步：
sudo dpkg --unpack /var/cache/apt/archives/apt_1.4.11_armhf.deb
sudo dpkg --configure apt
或重新安装apt：
wget http://ftp.univ-nantes.fr/debian-security/pool/updates/main/a/apt/apt_1.4.11_armhf.deb
sudo dpkg -i apt_1.4.11_armhf.deb
man dpkg:
--unpack package-file...
Unpack the package, but don't configure it. If --recursive or -R
option is specified, package-file must refer to a directory instead.

事实证明 AB 是对的 - coreutils 出了问题，重新安装它解决了这个问题：
# dpkg -i /var/cache/apt/archives/coreutils_8.26-3_armhf.deb
(Reading database ... 30176 files and directories currently installed.)
Preparing to unpack .../coreutils_8.26-3_armhf.deb ...
Unpacking coreutils (8.26-3) over (8.26-3) ...
Setting up coreutils (8.26-3) ...
接下来的 apt-get dist-upgrade 进展非常成功。我现在的猜测是，导致 Kodi 悲伤面孔循环的同一问题可能损坏了 microSD 文件系统，该系统在常规自动自检过程中丢失了太多块，导致部分 coreutils 丢失。
谢谢AB！！
