Received unexpected end-of-file from SFTP server

Hey, I am trying to set up a VM everytime I try to use SSH and login in Filezilla shows me this error. Can someone please help how to resolve it?

I am using this tutorial -

What OS version are you using?

Ubuntu 16.04.1

I’m afraid that tutorial only works with Ubuntu 12.04

Hey, This works with 16.04 also since I have also another VM running easy engine and I am able to use SSH successfully in that. But I had created that VM 2 months back did easyengine go through any change in these days and is it possible that I can install a older version of easy engine?
