I have Odoo community 14 installed in a Digital Ocean VPS (Ubuntu 20), and I want to install new modules from Odoo Apps Store. So far what I have done was:

1. download a module from aps.odoo.com
2. Create a repository on Github
3. Upload the module to the repository.
4. Clone the repository to the Odoo addons directory in Digital Ocean.
5. Update the list of apps in Odoo in developer mode.
6. Install the module in Odoo. When I want to install the system reports an error

This is the error:

Error:
