文件描述符 3 (pipe:[36899]) 在 vgs 调用时泄漏。父 PID 12657：/usr/sbin/grub-probe

Question

我遇到了标题中的错误，它发生在 grub 安装期间，也发生在 上dpkg --configure -a。我无法再更新，而且一旦遇到错误，shell 就没有响应。

谁能帮我？

Ctrl我又走了一步，C最终做了一些事情：

^Cdpkg: error processing package mdadm (--configure):
 subprocess installed post-installation script was interrupted
dpkg: dependency problems prevent configuration of ubuntu-server:
 ubuntu-server depends on mdadm; however:
  Package mdadm is not configured yet.

dpkg: error processing package ubuntu-server (--configure):
 dependency problems - leaving unconfigured

^C

尝试安装时mdadm我遇到了同样的问题......

Ctrl最终它在+之后完成C：

Cdpkg: error processing package mdadm (--configure):
 subprocess installed post-installation script was interrupted
dpkg: dependency problems prevent configuration of ubuntu-server:
 ubuntu-server depends on mdadm; however:
  Package mdadm is not configured yet.

会是什么呢……

离开终端一段时间后，我收到以下消息：

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=592834表明这只是一个外观问题（因此不确定你的 shell 是否没有响应）：

这只是来自“vgs”的过于冗长的调试。它抱怨 lvm 实用程序内部存在问题。在这种情况下，它确实无害。
