We’re far from being able to run on EL9 yet (see details in Path to Ruby 3.0, 3.1, EL9 and Ubuntu 22.04) and don’t have a date until when we can commit to be able to change that. So your choices are either getting a system with EL8 and run Foreman there or stick to the 3.3 branch which won’t get any updates once 3.5 is released.
