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 ├────────────────────────┐
│ │
│ Your system has UEFI Secure Boot enabled.
│
│ UEFI Secure Boot requires additional configuration to work with
│ third-party drivers.
│
│ 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.
│
│ <Ok>
老实说，我很难克服这一点。我需要关于我能做什么的帮助。
