I tend to just take the ubuntu (kubuntu) updates as released.  This time I was rebooting 
to go from the previous 5.4.0-65 kernel to the 5.4.0-66 kernel which was released about a 
month ago and installed on this laptop a few days ago.

I still have no clue as to what corrupted my /boot filesystem.    I did have the battery 
go completely flat while it was in suspend state about a week ago.  I can't see that being 
it as it did do a cold boot after that event.

I might try that on the weekend.

Being 5.10 it's probably not related to my problem.

Well I'm not looking forward to when my laptop can no longer boot the latest kernel.  I 
hope it's just a bug and not that the kernel must have newer hardware.  This Dell is about 
4 years old now.

While I was doing the fix this afternoon I was plagued by the 4k monitor this laptop has.  
In the default mode the boot-repair gui was minute!  Dealing with 4k was a real issue when 
I first got it but not now.
