Incorrect password for database users causes install/upgrade to fail
If you supply an incorrect password for one of the databases users (RBAC, console, PuppetDB), the installation or upgrade fails. However, in some cases it might appear that the installation or upgrade was successful. For example, if the incorrect password is supplied for the console database user, the installation or upgrade continues, and appears to succeed, but the console isn't functional.
