Problem:
Dependency problems with candlepin’s deps due to re-introduction of tomcat into EL8 repos
Expected outcome:
No dependency conflicts
Foreman and Proxy versions: 3.7.0
Foreman and Proxy plugin versions: 3.7.0
Distribution and version: CentOS 8-Stream for the last week or so
Other relevant data:
CentOS 8-stream includes the upcoming changes for RHEL 8 to re-include tomcat, which seems to conflict with previous dependencies that candlepin depends on. Thus, current CentOS 8-stream says the following with unqualified yum upgrade:
Error:

Doubtless this will be a complication for IdM/FreeIPA too, just wanted to report it here so it would be on the “radar” if it isn’t already
Thanks. We are aware and are coordinating with the team that manages the Tomcat packages. Right now the workaround to update a system hitting this error is to use --nobest so that it skips the Tomcat related packages and allows the rest of the packages to update.
Update: CentOS Stream 8 has fixed the Tomcat issue by cleaning up the bad packages and now updates of the system should be able to proceed as normal. That is, --nobest is no longer required.
The issue seems to still haunt my Foreman server. If the issue is resolved, how can I work out why I’m still seeing this issue?
