For those who come across this thread, I've found the exact list of changed and dropped package between rhel:7 and rhel:8: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/considerations_in_adopting_rhel_8/index#package-replacements_changes-to-packages Too bad that the "note" column is empty in the dropped package table. NO word about reason or possible alternatives. Also too bad that those drops were not advertised before release so developers could think about migrating there code. That would have helped me a lot if I had knew that docbook-utils-pdf would be dropped....I would have searched for an alternative long ago. Olivier.
