Getting error on uploading WordPress theme

Hi,

My name is John and I am trying to upload a WordPress theme to my website, I am doing so through my cPanel and it is not showing up in the CMS. And it also shows the following error “style sheet is missing”.

Any help would be appreciated.

Here is the theme I am after: https://touchwebsitesolutions.com/blog/2012/04/oakland-premium-responsive-wordpress-theme/
