Yes, this is an configuration issue. By default Ubuntu's root account is disabled and chfn should surely handle this configuration and just work. But it does not.
https://help.ubuntu.com/community/RootSudo tells to execute 'passwd -l root' to "re-disable" the root account. As I understand it this is Ubuntu's default configuration and chfn fails to work with it.
