In the process of using WordPress on your VPS, you can see the errors related to read/write data when installing plugin/theme as you mentioned in your question.
The reason this happens is due to errors in web server (nginx or apache) is not permission to read/write/delete or edit data. You will need to Cd (move) to your directory where you are storing data (eg /home/yourdomain.com/public_html/) and run the following command:

For Nginx on CentOS

chown -R nginx:nginx *

For Apache on CentOS

chown -R apache:apache *

For Nginx on Ubuntu

chown -R www-data:www-data *

For Apache on Ubuntu

chown -R www-data:www-data *

Hope it helps!
