Hello, currently Pulp team is rolling out big changes towards version 2.0. Katello testing build uses testing pulp repo, but from this week there is incompatible version of pulp there. Installation fails since pulp package was renamed to pulp-server. But if you would change require statement in our katello package, it would not work due to API changes. To install katello testing installation against pulp v1 disable repo named [pulp-testing]: vim /yum/repos.d/pulp-testing.repo And continue with install. We will be integrating Pulp V2 changes soon.
