8 – How can I fix site UUID does not match error during config import?

I’m getting this error below whenever I try executing the commands drush config-import staging on the CLI. I’m basically in the process of migrating a drupal 7 DB to Drupal 8 and currently following this guide since I’m still new with migration.
