最近，英特尔芯片出现错误后，我升级了我的 Debian Stretch 服务器。微代码更新正常，但update-initramfs挂了。因此，我将其关闭并尝试删除内核，然后再尝试重新安装。删除过程也挂了：
% dpkg --remove --force-depends linux-image-4.9.0-9-amd64
dpkg: linux-image-4.9.0-9-amd64: dependency problems, but removing anyway as you requested:
linux-image-amd64 depends on linux-image-4.9.0-9-amd64.
(Reading database ... 228637 files and directories currently installed.)
Removing linux-image-4.9.0-9-amd64 (4.9.168-1+deb9u2) ...
/etc/kernel/postrm.d/initramfs-tools:

它似乎挂在postrm脚本上：
% ps axuw |grep dpkg

我该如何修复它？
