Problem with installing Python on Zorin

I am trying to install the latest version of Python on Zorin system which camewith an older version of Python. First I got this error - E:dpkg was interrupted you must manually configure…then I got this message about secure boot. I don’t know how to proceed with this, Please help. Thank you!

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.
