 * Hi,
 * I am trying to update to wordpress 5.9 but when I update I get the following 
   error message. My file permissions are set to 755 so I dont think this is the
   issue.
 *     ```
       Downloading update from https://downloads.wordpress.org/release/wordpress-5.9-new-bundled.zip…
   
       The authenticity of wordpress-5.9-new-bundled.zip could not be verified as no signature was found.
   
       Unpacking the update…
   
       Could not copy file.: wordpress/wp-admin/options-head.php
   
       Installation failed.
       ```
   
 * Thanks and looking forward to any tips.
