To Reproduce
Try to sync a container repository in Katello after switching to the Pulpcore 3.17 repo, upgrading Pulp plugins, and migrating. Mine was prometheus/busybox on quay.io. I used the 'content only' mirroring policy and 'on demand' for a download policy.

Expected behavior
Create the distribution successfully.

This issue is currently blocking Katello's upgrade to Pulpcore 3.17.

Please try upgrading to pulpcore 3.17.6 and pulp-container 2.10.2. Does the problem persist after the upgrade?

[ianballou]

The problem is the same after upgrading pulpcore and pulp-container.

Here's an example of the data that we pass in to create the distribution:

#<PulpContainerClient::ContainerContainerDistribution:0x00007f38a4a3bce8 @base_path="default_organization-buttermilk_pancakes-library_hello-world", @name="library_hello-world-53555", @repository_version="/pulp/api/v3/repositories/container/container/1fe26685-e1ce-4998-ac34-3b1507052a43/versions/1/">

Can you trace the api POST request in the pulp api logs and verify that it is made as the admin user?
