 * “remove_core_updates” does not seem to be a core WordPress function. This may
   be a plugin or theme conflict. Please attempt to disable all plugins, and use
   one of the default (Twenty*) themes. If the problem goes away, enable them one
   by one to identify the source of your troubles.
 * If you can install plugins, install “Health Check”: [https://wordpress.org/plugins/health-check/](https://wordpress.org/plugins/health-check/)
   On the troubleshooting tab, you can click the button to disable all plugins and
   change the theme for you, while you’re still logged in, without affecting normal
   visitors to your site. You can then use its admin bar menu to turn on/off plugins
   and themes one at a time.

   everything was normal, when i update to wordpress 6.0, i get a notification
 * I also get a notification on wordpress `Previously closed automatic updates did
   not work. We will try again in the next release. The error code is download_failed.`
