By default, WordPress will not apply <a href="https://codex.wordpress.org/Configuring_Automatic_Background_Updates" rel="nofollow ugc">automatic background updates</a> if it detects a version control system (like Git or Subversion) in the WordPress directory or any of its parent directories.
WordPress does this because it assumes that if version control systems are present, the site owners have their own system in place for managing updates, and WordPress doesn’t want to mess with that.
However, minor updates can contain critical security vulnerability fixes, and those aforementioned site owners may consider the benefit of having minor releases automatically updated by WordPress greater than the risks of waiting too long to apply those updates themselves.
If that sounds like you, then you may wish to consider installing this option-free plugin.
Just activate when you need it.
Perhaps before a “disconnected” vacation when you don’t want to run the risk of a security update being released during it, and having no way of applying said update until your return.
Deactivate it when you don’t.

Forced Auto Updates

Apply automatic background updates for minor releases of WordPress core, even with version control systems present.

This plugin removes the WordPress update nag that appears at the top of all admin pages when a new version of WordPress is released.
Tired of WordPress nagging you about a new release? Maybe you already know about it and want to hold off on an update and would rather not see the update nag on every admin page you visit. Activate this plugin and be bothered no more!
The status of your version of WordPress (be it current or out-of-date) is still reflected in the footer of your admin pages and in the update count link in the admin bar.
And certainly, of course, I don’t advocate completely ignoring the fact that updates often contain fixes for critical bugs or exploits. However, there are various other means of learning about updates; and once known, not everyone is able or willing to update immediately.
