Update failed secure boot dbx

Since an attempt was made to update the secure boot dbx I get the following message when I start my computer.

Detailed errors from the package manager follow:

failed to build result for 362301da643102b9f38477387e2193e57abaa590

I have tried a number of possible solutions but no good results so far

This is a well known problem that have many users lately. There are many threads about this topic. You can take a look at this one to find a solution. The bug is not really solved yet by the zorin group.

But I don't have dual boot on my laptop. Or is it just the software with an error?
