Pulp

On a vanilla pulplift vagrant up when I run the unit tests all is fine. When I run the functional tests of pulpcore I get this error for every test:

======================================================================
ERROR: setUpModule (pulpcore.tests.functional.api.using_plugin.test_unlinking_repo)
