I encountered the same error when trying to create a database from scratch, but not with already created databases. In my case I scrolled up in the logs and found a record that marked an error in the logs. The registry is in odoo/addons/base/data/res_country_data.xml
I looked for the line that marked me in the logs, I commented on it and did the process of creating the DB again and it worked correctly.

I think you have a permission issue with odoo resources.

when you want to start odoo service, it uses addons from this path ".local/share/odoo/addons" so you must have the permission to read from this directory.

use these commands :

* I supposed that the ".local" hidden directory is located under home directory

1- cd ~

2- ls -la 

3- sudo chown -R user_name:group_name .local

** Note: change user_name and group_name with the ones who owned your odoo and odoo conf file.
