Integrity check failure on version.php - updated docker image 19.0.1 to 20.0.1

Nextcloud version (eg, 18.0.2): Docker image nextcloud:20.0.1
Operating system and version (eg, Ubuntu 20.04): ubuntu 18.04
Apache or nginx version (eg, Apache 2.4.25):
PHP version (eg, 7.1):

The issue you are facing: on the settings page under security and setup warnings it shows “some files have not passed the integrity check” list of invalid files show wrong hash value for version.php.

Is this the first time you’ve seen this error? (Y/N): YES

Steps to replicate it:

  1. Docker-compose down the nextcloud container
  2. Change image from 19.0.1 to 20.0.1
  3. Docker-compose up

$vendor = 'nextcloud';

Some how this resolved itself.
