Ошибка при установке vsftpd

Я пытался установить vsftpd FTP-сервер, но получить эту ошибку:

invoke-rc.d: unknown initscript, /etc/init.d/vsftpd not found.
dpkg: error processing package vsftpd (--configure):
  subprocess installed post-installation script returned error exit status
100 Errors were encountered while processing:
  vsftpd E: Sub-process /usr/bin/dpkg returned an error code (1)

Для установки его, я выполнил следующую команду:

sudo apt-get install vsftpd

Я использую Ubuntu 14.04 в виртуальной машине в виртуальном сервисе Cloud9.

И вот вывод для команды sudo apt-get install -f --reinstall vsftpd:
