Drop support for running on EL8 with Foreman 3.13

As RedHat 8 is still in support with maintenance support 2 ending in in 2029 there are / still will be paying users who I suspect will not appreciate moving away from 8 as quickly as Foreman 3.13, there will also be EL8 users who may need time to prepare greater than 3.13, how will users on RHEL’s expectations be handled and do we have a rough date planned for 3.13 as targeting a release is great but people tend to respond better to clearer target dates

Note this is only for the server aspect. Clients will still be supported.

As for the timeline, Foreman 3.12 Schedule and Planning has just been posted and I should have made it explicit here. 3.12 (the last release to support EL8) is planned to go GA 2024-09-17 has has roughly 6 months of support, so mid March 2025.

With RHEL Satellite being built on Katello, and that being supported on RHEL 8 is the 3.13 release aligned with a Satellite product release / update, I’ve been following my Satellite notifications (and also kicking my TAM) for support for RHEL9 and the feedback has been not on the roadmap, not for a while, etc. of there is no (to my knowledge) announced EOL alignment with Satellite versions won’t the code base for RHEL 8 compatibility still need to be maintained to support Satellite until it’s EOL and paid for support subscriptions expire or it goes into critical security update mode only, I suspect most orgs running Satellite will need a reasonable amount of time to plan and execute their migration.

You probably know Red Hat doesn’t communicate its road map here in upstream, but with my downstream hat on I can say that there should be sufficient hints in this thread. Also, your TAM should know. Let me follow that up privately.
