Strange text on the screen when starting the computer!(?)

Hi all.
MBP early 2011 ‘converted’ to Linux with Ubuntu Budgie 20.04.
Run it more or less perfectly for about a month. Do upgrades regularly (once a week in general).
A week ago something happened when I turn on the computer; When screen is still black and before the login set up is shown, a text in white is seen on the screen. It says;
‘Failed to set MokListRT: Invalid Parameter
Could not create MokListRT: Invalid Parameter
Importing MOK states has failed: import_mok_state0: Invalid parameter
Continuing boot since secure mode is disabled_’

This text is seen for about 3 seconds and then comes the normal login page (‘admin login’).
But even after the first login the text is seen again, but this time for only like 1 sec, then comes the regular login (user name).


Its a known bug:

So thoughts in the comments in that bug report.

I tried this;
sudo su -
cd “/boot/efi/EFI/ubuntu”
cp grubx64.efi shimx64.efi

and it looks like the white text on the black background is gone.

Just be aware when the next bug fix version of grub2 is released your changes will be overwritten.
