Problems creating a new user in Ubuntu

Question

I am experimenting with nginx+uswgi+Flask and am following this tutorial. However when I get to the portion for creating a new user for uswgi I am having troubles.

When I enter the command from the snippet the error I get is

$ sudo adduser -c 'uwsgi user,,,' -g nginx -d /nonexistent -s /bin/false uwsgi
Option g is ambiguous (gecos, gid, group)
Option d is ambiguous (debug, disabled-login, disabled-password)
Option s is ambiguous (shell, system)
...

I am by no means a ubuntu pro but after doing a little research I think the options I want are

$ sudo adduser -c 'uwsgi,,,' --group nginx --debug /nonexistent --system /bin/false uwsgi

however the error this returns is:

adduser: Only one or two names allowed.

here is my version information (if that helps)

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 12.04 LTS
Release:        12.04
Codename:       precise

So my question is what options should I be using to successfully create a uwsgi user such that I can complete the tutorial?

Solution

You are using wrong command. Use useradd instead of adduser:

sudo useradd -c 'uwsgi user,,,' -g nginx -d /nonexistent -s /bin/false uwsgi
