Why do I have creating storage link error

I try to install my laravel 5.7 application under Digital Ocean hosting and got error:

# php artisan storage:link

   ErrorException  : symlink(): No such file or directory

  at /var/www/html/votes/vendor/laravel/framework/src/Illuminate/Filesystem/Filesystem.php:228
    224|      */
    225|     public function link($target, $link)
    226|     {
    227|         if (! windows_os()) {
  > 228|             return symlink($target, $link);
    229|         }
    230| 
    231|         $mode = $this->isDirectory($target) ? 'J' : 'H';
    232| 

  Exception trace:

  1   symlink("/var/www/html/votes/storage/app/public", "/var/www/html/votes/public/storage")
      /var/www/html/votes/vendor/laravel/framework/src/Illuminate/Filesystem/Filesystem.php:228
