Can not update from 9.1.0 to 9.1.2 - Error [UnexpectedValueException]

Hello,
I just wanted to update my ownCloud to 9.1.2.
Currently I have the version 9.1.0 running on.
If I want to start the updates in the admin area, I get this message immediately:

"
[UnexpectedValueException]
Could not parse a response for config: list. Please check if the current shell user can run occ command. Raw output:
Not allowed
This hotel is located in the city center.
"

What can be the cause, what is the remedy?

Best wishes

I have the solution.
