我在尝试在 Ubuntu 20.04LTS 中安装一些软件包时不知何故陷入了某种奇怪的状态。它说软件包已经安装，然后尝试安装或更新 GRUB。起初它弹出一个紫色屏幕，警告 /dev/sda1 不是 EFI 分区（正确），继续可能会导致启动失败。我说不，它就进入了一个循环，一遍又一遍地询问，直到我关闭终端（ctrl+C 不起作用）。我不得不杀死一些与 apt 相关的进程才能再次使用 apt，然后它坚持让我修复 dpkg 状态：
sudo dpkg --configure -a
Setting up grub-efi-amd64-signed (1.173.2~20.04.1+2.04-1ubuntu47.4) ...
debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable
dpkg: error processing package grub-efi-amd64-signed (--configure):
installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 1

Errors were encountered while processing:
grub-efi-amd64-signed
我第一次运行该命令时，它又陷入了无限循环。我重新启动后，它又出现了上述错误。现在，每当我尝试安装某些东西时，我都会遇到这种情况：
sudo apt-get install freerdp2-x11

freerdp2-x11 is already the newest version (2.2.0+dfsg1-0ubuntu0.20.04.3).
