I found a solution:

just use "sudo" in front of vi hosts (it will ask for the admin password) By doing this, I basically open the hosts files with administrator privileges:



$ sudo vi hosts

and after modifications it :wq

works just fine!

Start Terminal

  $ sudo vi /etc/hosts


and after improvements

 :wq!

My problem was that I was running sudo vi etc/hosts

instead of sudo vi/etc/hosts
