By default, Ubuntu and it's variants do not set a password for root
which has the the affect of preventing anyone from logging in as root. 
If you don't need root then don't enable it as there are plenty of ways
around this and thus prevents people from brute-forcing the root password.

To run a command with root privileges, you are correct that sudo is the
way to do it and then append the command; sudo ./setup.sh
Before you do that, you may want to try; bash -v ./setup.sh
that should spit out some information about why the script is failing. 
I suspect it is trying to copy something to a location that needs
root/sudo access.

Just to be curious, what is this script supposed to be installing?  Is
it form a source you trust?  I usually open a script from a source I am
not familiar with and read through it so see if it is going to do
something stupid.
