O.K. I can db:migrate:

API controllers newer than Apipie cache! Run apipie:cache rake task to regenerate cache.

Installed package list was still short after that. Running katello-package-upload -f on a centos 7 content host seems to fix that. For CentOS 8 (no katello-package-upload available) I have (re)installed or updated any package and that seems to update that either.

katello-package-upload -f still causes the exception:

Now it looks good for all content hosts and no updates pending. I’ll see what happens when the next updates appear in the repositories. At the moment it looks good.
