Trying to install OPMS 10 on RHEL 7 and it is failing at the end of the installation process with the following:
Installation failed Could not retrieve fact='yum_proxy', resolution='': undefined method `empty?' for "":String
The failures all seem stem from the following message in the puppet log
Error: Package: 2:container-selinux-2.66-1.el7.noarch (rhel-7-server-extras-rpms)
Requires: selinux-policy-base >= 3.13.1-192
Which relates to https://bugzilla.redhat.com/show_bug.cgi?id=1566578
Which has the following resolution
This is not a bug.
Error: Package: 2:container-selinux-2.55-1.el7.noarch (rhel-7-server-extras-rpms)
This package is only available in rhel-extras.
If you are using items in extras, you are expected to be on the latest release, per: https://access.redhat.com/support/policy/updates/extras/ You could use an unsupported solution of version locking packages to get your updates to continue, or perhaps a repo-override via subscription-manager to point extras at the 7.4 tree (which does exist, but is not configurable via release within sub-man/entitlements).
