Comment (by zippy1970):

 In **class-wp-filesystem-ftpext.php** I replaced the ''exists()'' function
 with my own version (below) and the update succeeded without a hitch.

 {{{#!php
 <?php
         public function exists( $file ) {
           $retval = false;

           $list = ftp_nlist( $this->link, $file );
           if( ! empty( $list ) ) {
             // if ftp_nlist returns *something*, the file or directory
 exists, on any FTP server
             $retval = true;
           } else {
             // if ftp_nlist returns nothing, either the file/dir doesn't
 exist or it's a file and
             // the FTP server's NLST command doesn't support globbing
 (i.e. Pure-FTPD > v1.0.47)
             // Check if it'a file
             if( ftp_size( $this->link, $file ) >= 0 ) {
               $retval = true;
             }
           }
           return $retval;

         }

 }}}
