POS can not be configured

Hello,

I try to configure POS like mentioned here: Not Found. But I can not find the link to this menu nor do i find POS via the search bar. I only have these options:

Is my ERPNext configuration buggy or which point do I miss here?

Best regards

Does your user have user/role permissions to configure POS?

I think I did not completely install ERPNext. I used this guide How to Install ERPNext ERP Platform on Ubuntu Linux with Nginx - Geek Rewind to install ERPNext. But this guide is missing one crucial point. It is only installing frappe/bench but not the erpnextapp as mentioned here GitHub - frappe/bench: CLI to manage Multi-tenant deployments for Frappe apps.

So I will continue with completing my installation and come back in case of problems.
Thank you so far.
