Ha! When you wrote "operator" previously, I didn't realise you were literally entering a user name of "operator", I thought you were using "operator" in the same way some people write "/home/user" or "/home/username" when they mean /home/<user name>.
Having said that, I had no idea that using the text string "operator" as a user name would cause the problem you experienced.
How did you discover that using "operator" for a user name was the cause of the problem? Trial and error, or Google?
Just out of curiosity, why did you choose to use "operator" as a user name? Wouldn't something more personal be better? "/home/operator" is not as immediately distinctive as e.g. "/home/alshain". If you want to set up the PC for multiple users, it's better to create multiple user accounts, and they can be set up to have access to each others files if you want.
For example, one could set up the accounts so that users "fatherbear", "motherbear" and "babybear" are members of the group "porridge" but user "goldielocks" is not.
Anyway, glad you are now set up correctly. Better than hacking an incorrect installation, and you have the satisfaction of finding a bug, to boot.
