ubuntu更新后出现grub-efi-amd64 not configure yet错误

问题： 在每次用apt-get或者pip安装完软件后，出现package grub-efi-amd64 is not configured yet 和dpkg: error processing package grub-efi-amd64-signed(--configure): 的错误。

2 not fully installed or removed.

After this operation, 0 B of additional disk space will be used.

Setting up grub-efi-amd64 (2.02~beta2-22ubuntu1.5) ...

dpkg: error processing package grub-efi-amd64 (--configure):

 subprocess installed post-installation script returned error exit status 127

dpkg: dependency problems prevent configuration of grub-efi-amd64-signed:

 grub-efi-amd64-signed depends on grub-efi-amd64 (= 2.02~beta2-22ubuntu1.5); however:

  Package grub-efi-amd64 is not configured yet.

dpkg: error processing package grub-efi-amd64-signed (--configure):

 dependency problems - leaving unconfigured

No apport report written because the error message indicates its a followup error from a previous failure.

                           Errors were encountered while processing:

 grub-efi-amd64

 grub-efi-amd64-signed

E: Sub-process /usr/bin/dpkg returned an error code (1)

解决方法：

$sudo gedit //var/lib/dpkg/info/grub-efi-amd64.postinst

在set e后， 下一行，输入： exit 0

保存后，在终端运行命令：

$sudo dpkg --configure -a

原因：

这是ubuntu的一个bug, 是在更新后postinstall script没有很好的clean up. 以上解决方法强制提前退出。
