我遇到了问题apt-get。当我尝试更新系统时发生了一些错误，当我尝试修复它时，apt-get install -f它失败并显示以下消息：

如果我使用以下命令检查服务状态，service grub-common status则会得到以下信息：

grub-common.service
  Loaded: not-found (Reason: Not a directory)
  Active: inactive (dead)

我搜索了 grub-common，apt search "grub-" |grep inst得到了以下信息：

grub-gfxpayload-lists/xenial,now 0.7 amd64 [installed]
   Handles update-grub for ec2 instances
grub-pc/xenial-updates,now 2.02~beta2-36ubuntu3.1 amd64 [installed]
grub-pc-bin/xenial-updates,now 2.02~beta2-36ubuntu3.1 amd64 [installed]

我如何解决它？

Failed to stop grub-common.service: Unit grub-common.service not loaded.
invoke-rc.d: initscript grub-common, action "stop" failed.

包管理器正在尝试停止grub-common服务，但您的系统处于不一致状态，因此失败。的预删除脚本grub-common位于此处：

/var/lib/dpkg/info/grub-common.prerm

在我的系统上它以以下部分结束：

# Automatically added by dh_installinit
if [ -x "/etc/init.d/grub-common" ] || [ -e "/etc/init/grub-common.conf" ]; then
        invoke-rc.d grub-common stop || exit $?
fi
# End automatically added section

如您所见，它正在测试两个文件（/etc/init.d/grub-common和）中任一个是否存在，如果存在则/etc/init/grub-common.conf执行。invoke-rc.d grub-common stop此命令失败。

路线

重命名上述文件以保留它们但“停用”它们：

sudo mv /etc/init.d/grub-common /etc/init.d/grub-common.bak
sudo mv /etc/init/grub-common.conf /etc/init/grub-common.conf.bak

如果这两个命令之一失败，请不要担心。

完成此步骤后，您应该能够使用以下命令修复软件包：

sudo apt-get install -f
