Good.
Yes, I created a root password and a user account.
Good; that is all you need. Unless others have access to the machine and you have unusual concerns regarding security, forget about sudo.
... when logged in as a user and type sudo or su apt-get update it then should ask for the root password and then does it???s thing. At least that's how it worked when I used Debian before.
When logged in as a normal user, type su; Debian should request the root password. Upon entering the root password, you should have the root prompt (#). Then execute "apt-get update". When you are finished, execute "exit", which should return you to the normal user prompt ($). I normally do maintenance via synaptic. As a normal user I execute synaptic, and synaptic asks for the root password. RLH
