 === Environment
 OS: Windows 10 (Local by Flywheel)
 PHP: 7.4.1 (also on 7.3.5 and 5.6.39)
 Server: Apache
 Database: MariaDB 10.4.10
 Browser: Chrome 96.0.4664.45

 === Steps to reproduce
 1. Install WordPress 5.8.2 using Local by Flywheel with PHP 7.4.1, Apache
 and MariaDB 10.4.10.
 2. Visit `Database -> Adminer` in Local by Flywheel.
 3. Select all the database tables and "Drop" them.
 4. Download a copy of WordPress 5.0.4 from
 [https://wordpress.org/wordpress-5.0.14.zip here]
 5. In Local by Flywheel, click the arrow beside your site's path.
 6. Navigate to the `app/public` directory.
 7. Delete all files except for `wp-config.php`.
 8. Open `wordpress-5.0.14.zip` and extract all files into the `app/public`
 directory.
 9. In Local by Flywheel, click "Admin".
 10. Proceed through the installation process and login.
 11. Navigate to `Appearance -> Plugins -> Add New`.
 12. Install and activate the `WordPress Beta Tester` plugin.
 13. Navigate to `Tools -> Beta Testing`.
 14. Click "Bleeding Edge" and click "Save".
 15. Click "Beta/RC Only" and click "Save".
 16. Navigate to "Dashboard > Updates".
 17. Run the core update.
 18. Navigate to `Appearance > Plugins`.
 19. Click "Update now" for `Hello Dolly`.

 If the environment has been matched and the update fails, this issue is
 legitimate.
