Did you edited the file? Can you remove the app and install it again please?

[PunchIng]

It's the original file that didn't cause any issues before the update of Nextcloud to 20.0.3 I removed the app and re-installed it - the warning was / is still the same...

[PunchIng]

Question: Is it possible that the update to Nextcloud 20.0.3 replaced a file containing the hash of the ContactsController.php file? Could that file containing the hash be restored?

No, it's all depending on the contacts app. I find i weird. Can you retrigger a integrity scan from occ?

[PunchIng]

This is the result of occ integrity:check-app --path=/nextcloud/apps/contacts contacts

• EXCEPTION:
  • class: OC\IntegrityCheck\Exceptions\InvalidSignatureException
  • message: Signature data not found.

[PunchIng]

No idea why, but replacing the ContactsController.php file once more solved the issue. I downloaded the zip folder from apps.nextcloud.com/apps/contacts and transferred only the incriminated file - via ftp in binary mode (!) - fixed!
