Error installing Virtualmin

Hi, I had installed Virtualmin until 2 hours ago, when I decided to format my VPS and re-install it by some errores with rouncube’s script on my sub-servers.
I downloaded from official page (GPL version) and when I run “sudo /bin/sh” or “sudo sh” it gives me an error and I can’t install it.
I tryed to ping virtuyalmin and does it works. You can see my console on next image:
Can you help me to solve that problem?
