Hi,
From the shared message, it seems you have deleted the system generated USD currency and manually created a currency with name USD.

Now when you are trying to upgrade the base module, system trying to create the deleted currency which is USD, in order to solve the error, open the currency menu and search for USD currency and set its external ID as:  base.USD

By setting this external id for existing USD, you can solve the issue.

Other option is two delete the current usd currency (not sure if it is used in db or not), if no delete the currency and upgrade base.


Thanks

The above server error caused the following client error:

        at XMLHttpRequest.<anonymous> (https://green-iceberg-as-team.odoo.com/web/assets/468fcc3/web.assets_web.min.js:2914:13)

 I updated the data base aswell just now. To see if there are something wrong in the old database for Odoo.
