Failed to set MokListRT: Invalid Parameter error comes up while running Ubuntu 20.04 in Mac book Pro (2013) for a few months now and this has happened to me whenever I boot into Ubuntu. How could I make this disappear?

P.S Let me put the words in the picture into written issue,

Failed to set MokListRT: Invalid Parameter in Ubuntu

“Failed to set MokListRT: Invalid Parameter
Could not create MokListRT: Invalid Parameter
Importing MOK state has failed: import mok_state() failed: Invalid Parameter
Continuing boot since secure mode is disabled”

So, How to FIX this issue of Failed to set MokListRT: Invalid Parameter?

This looks to be a UEFI bootloader related issue.

In some cases there were no loader selected at all or in some cases it was booting to a dead boot slot in grub throwing this error on the display.

Change the efibootmgr timeout time

You can change the efibootmgr timeout so that it will populate a list of installed OS so that you can select which one to start!

efibootmgr -t 5

Executing the above command has resulted showing a list of installed OS to select while booting:
