启动和更新 Ubuntu Server 20.04 时出现 GRUB 错误“无效环境块”

当我启动我的 Ubuntu 20.04 服务器（virtualbox vdi，local dev）时，出现以下错误：

Error: invalid environment block.
press any key to continue....

现在，当我运行更新时，所有内容均可正确安装，但 grub 除外，它会引发此错误：

dpkg: error processing package grub-common (--configure):
 installed grub-common package post-installation script subprocess returned error exit status 1
dpkg: dependency problems prevent configuration of grub2-common:

我尝试过的解决方案

  1. 我从系统磁盘启动了服务器并e2fsck /dev/sda2 -y按照建议运行错误：环境块无效。按任意键继续（Ubuntu 20.04 ZFS），但没有运气。

  2. 跑步

    sudo dpkg --configure -a && sudo apt --fix-broken install

  3. 跑步

    dpkg --purge --force-depends grub-common && apt-get -f install

有小费吗？

答案1

似乎有一个损坏的/boot/grub/grubenv。这种情况的常见原因可能是硬件缺陷、电缆松动或可能在 grub 中关闭电源。
删除文件并运行，sudo grub-editenv list同时创建一个空文件，并允许您继续。

答案2

我没有足够的信息，但您可以随时尝试的常见方法是：

sudo dpkg --configure -a
sudo apt --fix-broken install

或这个：

dpkg --purge --force-depends grub-common
apt-get -f install

或者也许只是这个有效：

apt update & apt-upgrade
