Hi,
I’m not able to install latest version of katello-agent on Fedora 27 because Katello 3.6 repo is missing packages, only “repo” rpms are availabe at https://fedorapeople.org/groups/katello/releases/yum/3.6/client/f27/x86_64/
Seems there is the same issue for EL6 (see https://community.theforeman.org/t/packages-missing-in-katello-3-6-client-for-el6/8874
Thanks.
