Даже хочется поставить "fun" topic, но тут не до смеха под Ubuntu:

    # adduser user
    Adding user `user' ...
    Adding new group `user' (1000) ...
    Adding new user `user' (1000) with group `user' ...
    Creating home directory `/home/user' ...
    Stopped: Couldn't create home directory `/home/user': File exists.

    Removing directory `/home/user' ...
    Removing user `user' ...
    Removing group `user' ...
    groupdel: group 'user' does not exist
    adduser: `groupdel user' returned error code 6. Exiting.
