Got error 'Bad counter handle' by update checksums


When I choose:

Update checksums and sign all files in /boot

I get the following error:

‘Bad counter handle’ (0x45) from TPM_IncrementCounter.

Failed to sign default config

Is anyone familiair with this error and knows how to solve this?

Thanks in advance.
