Ubuntu Server 9.10 doesn't add user after install

[Seth]

Hi,
I downloaded Ubuntu Server to try on my iMac G3, the install seems to  
go fine execpt that it never adds the user when it is finishing the  
install. I made sure that I wrote down the password and login, but it  
said that there was no such user (or something to that nature).
I have installed Ubuntu Server 6.06 for now and it seems to be working  
fine, but I would like to know if this is a bug in the PowerPC edition  
of Server? If there is a way to fix it, I would thank you guys so much.
