After the installation of Ubuntu Server 16.04 login as root is not permitted. As I am testing various Linux distros in a lab situation it is easier to use the same login and for configuration it simpler without sudo. So to allow root login do the following
Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully
Login with root is now possible, to allow login with root from puTTY we can issue the following command
Or you can change it manually to yes at line 28
27 LoginGraceTime 120
28 PermitRootLogin yes
29 StrictModes yes
We can now use puTTY to get the updates
And then update the system with the upgrade command
