I tried the first usermod command you listed however I got "sudo: unable to resolve host HostName" and "usermod: user TheNameIWantToChange is currently used by process 2559"

can you provide the output of ps -q 2559? In any event, it seems like the user TheNameIWantToChange already exists on your system. To make it clearer, can you list all the users you created (not system created users)?
