DATA CONFLICT! Your old ‘/var/www/nextcloud/data’ directory can be found in ‘/var/www/nextcloud/.data_2024-04-19T1713539287’ after the restore script is done. The new ‘/var/www/nextcloud/data’ directory will be restored from the backup. You can manually merge these directories with this command (run nc-fix-permissions and nc-scan afterwards): cp -rn ‘/var/www/nextcloud/.data_2024-04-19T1713539287/’* ‘/var/www/nextcloud/.data_2024-04-19T1713539287/’.[!.]* ‘/var/www/nextcloud/data/’

Cleanup…
Rollback successful. Nothing was updated

I think you should describe you installation with more details.
Looks you are using ncp which comes with some specialities.

Mittlerweile hat es geklappt.
Die Reihenfolge der Updates wars.
Danke für Eure Hilfe.
