This might be a very basic linux fundamentals question, apologies ahead of time if this has been answered 1,000 times.
How do I workaround the Icinga Web 2 php dependencies on the rh-php packages? I’m on Oracle linux and the requirement to install these is subscription-manager to enable rhn-scl repository and a couple others, but subscription-manager is deprecated on Oracle Linux b/c it’s Oracle Linux… 
I get the following package dependency errors:
