Foomatic Database could not be loaded

I would checkout the printer configuration and right by the field brand and model to the button change.
After that the message appears "searching for drivers" "Nach Treibern wird gesucht". In the main window the option "Drucker aus Datenbank auswählen" is activated.
The Search Window stands open for hours, nothing happen.
What can I dou to fix this problem?

From websearch using "Foomatic printer driver Ubuntu 20.04" I see this:
the database is in Ubuntu Universe repository.
Do you have that respository enabled?

I'll checkit out. Thanks
