I have found that version 2.2.8 that comes with Ubuntu 18.10 works fine. I downloaded and installed it into Ubuntu 18.04 from https://launchpad.net/ubuntu/+source/cups/2.2.8-5ubuntu1.2 and it asked for login and all admin functions were working as expected.

But I cannot add the printer if I go directly to http://localhost:631/admin and bypass the login. If I need to change any defaults of the printer through the same pages it gives me the "Unauthorized" and will not change anything. I can change it in Firefox and the printers control panel.
