I'm having a problem installing the latest version of CiviCRM on WordPress 4.8.2 (Ubuntu 16.04.3 LTS, Apache 2.4.18, PHP 7.0).
Steps to Reproduce: 1) Log in to the WordPress site's administrative interface. 2) Click "Add New" under "Plugins" on the administration menu. 3) Click "Upload Plugin," then browse to and upload the plugin's Zip file.
Output: Unpacking the package… Could not extract file from archive. civicrm/civicrm/packages/kcfinder/themes/dark/img/files/big/..png
Expected Results: The package should have extracted and installed with no errors.
