Rubygem-rkerberos currently not installable on EL7.5

As some of you might have noticed, rubygem-rkerberos is currently not installable on EL 7.5, as it depends on an older that is no longer part of EL 7.5.

This is tracked upstream in EPEL BZ #1563125 and there is an update (FEDORA-EPEL-2018-90207015c0) available for testing.
We are tracking this in #23241, you can follow the redmine issue for updates.

If you are running Foreman and want to upgrade the base OS to EL 7.5, you can either hold off updating libkadm5 (and all the related Kerberos packages) or try the build from the update above and vote for it on the Fedora Updates System.

From the looks of rubygem-rkerberos-0.1.3-6.el7 has been pushed to the Fedora EPEL 7 stable repository as of 2018-05-03

This is causing Katello 3.5 and 3.6 installs to fail today 2018-05-04 on “CentOS Linux release 7.4.1708 (Core)”

# yum install katello

–> Finished Dependency Resolution
Error: Package: rubygem-rkerberos-0.1.3-6.el7.x86_64 (epel)
Error: Package: rubygem-rkerberos-0.1.3-6.el7.x86_64 (epel)

This particular issue was not present yesterday 2018-05-03.

Workaround is to install rubygem-rkerberos-0.1.3-5.el7 prior to running “# yum install katello”.

Package rubygem-rkerberos-0.1.3-5.el7 can be found here:

Another workaround is to use the repo CentOS-CR.repo
