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).
