Hi,

The error message indicates that the module auth_user_case_insensitive cannot be installed because one of its dependencies is missing. This module is part of the OCA (Odoo Community Association) server-auth repository and relies on core Odoo modules such as base and auth_signup. If those are not installed or if the OCA repository is not available in your addons path, Odoo will mark the module as having inconsistent states.

To resolve this, you need to make sure the OCA/server-auth repository is available in your addons directory. On Linux, this can be done by cloning the repository from GitHub, while on Windows you can download and unzip it directly into your addons folder. Once the repository is added, update your Odoo addons path, restart Odoo, and refresh the apps list. After doing this, you should be able to install auth_user_case_insensitive without the dependency error.

Hope it helps

Hello dina

The module you are trying to install a module which depends on another module called auth_user_case_insensitive

odoo cant find the module  auth_user_case_insensitive. 

You either dont have this module in your addons path or there is a problem in configuring your addons path 

you can find and download this module in here https://apps.odoo.com/apps/modules/18.0/auth_user_case_insensitive
