与安全启动相关的 apt-get 和 dpkg 问题

我最近在使用 Ubuntu 时遇到了麻烦。每当我尝试sudo apt get某事（在本例中为 python 3）时，我都会收到错误消息：dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem

所以我输入命令，经过漫长的过程后，我收到了这条消息：

Configuring Secure Boot ├────────────────────────┐

 │ 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      
 │ generated. This key now needs to be enrolled in your system's firmware.     
 │                                                                             
 │ 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.                  
If you proceed but do not confirm the password upon reboot, Ubuntu will     
 │ still be able to boot on your system but any hardware that requires         
 │ third-party drivers to work correctly may not be usable.                    
 │

老实说，我很难克服这一点。我需要关于我能做什么的帮助。
