The key part from the error is:

The theme is missing the style.css stylesheet.

WordPress docs on Main Stylesheet says:

In order for WordPress to recognize the set of theme template files as a valid theme, the style.css file needs to be located in the root directory of your theme, not a subdirectory.

I would suggest you to unzip the theme and look for style.css. If the file is there open it; there should be some commented lines that will look similar to these:

/*
Theme Name: Twenty Seventeen
Theme URI: https://wordpress.org/themes/twentyseventeen/
Author: the WordPress team
Author URI: https://wordpress.org/
Description: Twenty Seventeen brings your site to life with immersive featured images and subtle animations. With a focus on business sites, it features multiple sections on the front page as well as widgets, navigation and social menus, a logo, and more. Personalize its asymmetrical grid with a custom color scheme and showcase your multimedia content with post formats. Our default theme for 2017 works great in many languages, for any abilities, and on any device.

*/

The following fields should be in every main stylesheet: Theme Name, Author, Description, Version, License, License URI and Text Domain. If any of the mentioned fields are missing I strongly recommend contacting the theme provider.

If you're the owner or the author of the theme make sure to include the mentioned lines and to include the style.css file in the root directory of the theme before uploading the archived theme to your WordPress installation.

Also, make sure to read more on Main Stylesheets here: https://developer.wordpress.org/themes/basics/main-stylesheet-style-css/

style.css file is a required file during wordpress theme installation. Because in your style.css file you have to define your theme related information.

The theme package is missing an important theme file (style.css), which is required. An anatomy of a WordPress Theme consists of required and recommend files.

See developer.wordpress.org/themes/release/required-theme-files and codex.wordpress.org/Theme_Development

This simply means that you should contact the developer(s) of the theme and ask them to fix this issue.

If there is style.css file present and even though you are facing issue then it must be a folder permission issue. Check with wp-content/themes folder permissions.If you've migrated the website from one server to another server then this folder permission issue comes. Check with hosting provider or server administrator. Or else change the permission to 777.
