Description of problem:

Package "rh-sso7-keycloak-server-18.0.6-1.redhat_00001.1.el8sso.noarch" obsoletes some ancient "eap7-wildfly-modules" releases:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

1. rpm -q --obsoletes rh-sso7-keycloak-server-18.0.6-1.redhat_00001.1.el8sso.noarch
   eap7-wildfly-modules <= 0:7.3
   • • • • • • • 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

Trying to install both rh-sso7-keycloak-server-18.0.6-1.redhat_00001.1.el8sso.noarch and eap7-wildfly-modules-7.4.10-6.GA_redhat_00002.1.el8eap (latest, not obsoleted at all) on the system, the eap7-wildfly-modules-7.4.10-6.GA_redhat_00002.1.el8eap cannot be installed, unless full release is explicitly specified:

1. The following doesn't install "eap7-wildfly-modules" at all

-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

1. yum install rh-sso7-keycloak-server eap7-wildfly-modules
   • • • • • • • 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

2. The following installs "eap7-wildfly-modules"

-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

1. yum install rh-sso7-keycloak-server eap7-wildfly-modules-7.4.10-6.GA_redhat_00002.1.el8eap
   • • • • • • • 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

I understand this is somehow expected because libsolv doesn't check the obsoleted part ("0:7.3") by default. Please correct me if I'm wrong.

Still this is an issue, because after installing the packages (using "2." method), any new "yum update" transaction will fail:

-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

1. yum update
   [...]
   Error:
