Nextcloud 24.0.7: Ugrade to 24.0.8 seems to do nothing

Nextcloud version (eg, 20.0.5): 24.0.7
Operating system and version (eg, Ubuntu 20.04): Debian 11.0.5
Apache or nginx version (eg, Apache 2.4.25): 2.4.54-1
PHP version (eg, 7.4): 7.4.33--1

The issue you are facing:

Setting show that a new version ist available (24.0.8). Starting upgrade nearly puts me immediately to the main page. Review show it is still at 24.0.7.
Output of cmdline upgrade process:

www-data@nextcloud:~/html$ php /var/www/html/updater/updater.phar 
Nextcloud Updater - version: v24.0.0beta3-1-g67bf13b dirty

Current version is 24.0.7.

Should the "occ upgrade" command be executed? [Y/n] y
Nextcloud is already latest version

Keep maintenance mode active? [y/N] 
Maintenance mode already disabled

Maintenance mode is disabled

A check reveals “not upgraded”:

www-data@nextcloud:~/html$ php occ status
  - installed: true
  - version: 24.0.7.1
  - versionstring: 24.0.7
  - edition: 
  - maintenance: false
  - needsDbUpgrade: false
  - productname: Nextcloud
  - extendedSupport: false

The steps above (check, download, verify, …) does not require any time. The download seems not being really executed.

Is there a way to force the upgrade ?

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