Code integrity check failed after update to Nextcloud 12 (caused by direct_menu)

[stweil]

I upgraded an installation which had the Direct Menu app installed to Nextcloud 12 and got an error message from the code integrity check ("Bei der Code-Integritätsprüfung ..."). Here is the full error report:

Technical information
=====================
The following list covers which files have failed the integrity check. Please read
the previous linked documentation to learn more about the errors and how to fix
them.

Results
=======
- direct_menu
        - EXCEPTION
                - OC\IntegrityCheck\Exceptions\InvalidSignatureException
                - Certificate is not valid.

Raw output
==========
Array
(
    [direct_menu] => Array
        (
            [EXCEPTION] => Array
                (
                    [class] => OC\IntegrityCheck\Exceptions\InvalidSignatureException
                    [message] => Certificate is not valid.
                )

        )

)

As the features of direct_menu are now part of Nextcloud 12, I removed the apps/direct_menu directory from the installation and repeated the integrity check. That fixed the integrity error message.

The update to Nextcloud 12 should handle that case on its own.

A code of the removed directory which had caused the problem is available online.

Just remove the direct_menu app since it is not compatible with 12.
