Urgent: I have messed up FTP in Ubuntu VM

[Marcello.ligi]

I was trying to fix some issue with FTP on my Ubuntu Linux, I have tried to uninstall and reinstall but I might have mess it up! I have done the following commands:

Uninstall ftp

To remove just ftp package itself from Ubuntu 16.04 (Xenial Xerus) execute on terminal:

sudo apt-get remove ftp

sudo apt-get autoremove ftp

sudo apt-get purge ftp

sudo apt-get autoremove --purge ftp

I have tried to reinstall it but now when I try FTP localhost it says: Connection refused

I have reinstalled also vsftpd following the guidelines but nothing.

I am not a Linux user and now I'm totally lost.
