see screen...There is no need to code anything, but you will find out the reason why it is not updated, I think there will be a problem with CRON

For example in UNA logs- upgrade.log should be this if there is an update:

--------- 2024-09-11T19:25:01+00:00

14.0.0.B2-14.0.0.RC1 upgrade will be applied

Files permissions are ok and can be overwritten

Files copying successfully completed

Deprecated files were successfully deleted or there is no files to delete

System files hash was successfully updated

System SQL script was successfully executed

The following languages will be affected for system:

 - No languages will be affected

System after update custom script was successfully executed

Look on your server folder Log /zzzzzz.zzz/web/log/ error.log to see what errors there are
