系统崩溃，终端显示“配置安全启动”框

我尝试使用 - 升级 xfce 桌面

sudo apt-get upgrade xfce4

由于未知原因，该过程未完成。每当我尝试发出sudo apt-get命令时，它都会导致 -

dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

现在我的整个系统没有图标，一个也没有。某些软件包必须尚未安装。一些研究产生了两种解决方案。

sudo dpkg --configure -a

这导致了一个框（我不知道它是错误框还是说明框。）我尝试截屏，但是唉！也受不了。我在这里复制粘贴了文本。

Configuring Secure Boot   
 │ Your system has UEFI Secure Boot enabled.

 │ UEFI Secure Boot requires additional configuration to work with

 │ The system will assist you in configuring UEFI Secure Boot. To permit       
 │ the use of third-party drivers, a new Machine-Owner Key (MOK) has been

 │ To ensure that this change is being made by you as an authorized user,      
 │ and not by an attacker, you must choose a password now and then confirm     
 │ the change after reboot using the same password, in both the "Enroll        
 │ MOK" and "Change Secure Boot state" menus that will be presented to you     
 │ when this system reboots.

请指导我该怎么做，是否应该重新安装整个系统，或者仍然有一些方法可以解决这个问题。
