Problem while updating modules

Question

I'm running a Drupal website for a while but suddenly and for an unknown reason the website become unable to update modules via the back office. The download of the modules goes good but when I click to the button to update the database I got an error page and when I see the recent reports logs I have that:

UpdaterException: Unable to determine the type of the source directory. in Updater::factory() (line 99 of ../www/includes/updater.inc).

Is there any solution for that problem?
Notice: I'm using Zeus server instead of Apache.

It looks like the directory it's expecting the source to come from doesn't exist. Here's the snippet of code which causes the exception to be thrown.

if (is_dir($source)) {
  $updater = self::getUpdaterFromDirectory($source);
}
else {
  throw new UpdaterException(t('Unable to determine the type of the source directory.'));
}

When updating this is the default directory: $directory = 'temporary://update-extraction-' . _update_manager_unique_identifier();

Make sure your defined temporary folder in the file system can be written to by Drupal.

If all else fails, manually update your modules via file transfer.
