Bug 2124637

Description of problem:

A long-awaited feature has landed in the pulp of satellite 6.12 i.e. https://github.com/pulp/pulpcore/pull/2149.

Using "pulpcore-manager analyze-publication" we are now able to see filename, artifact location and pulp href of the artifact for any given publication id or distribution path. 

But EVEn if it works, it displays a WARNING and it's not possible to use "--tabular" option as well.


Version-Release number of selected component (if applicable):

Satellite 6.12
python39-pulpcore-3.18.6-2.el8pc.noarch


How reproducible:

Always


Steps to Reproduce:
1. Install a Satellite 6.12 with Organization name RedHat

2. Enable RHEL 7.9 Kickstart repo and sync it with immediate download policy.

3. Find out it's distribution_path:

# echo "select relative_path from katello_repositories where relative_path like '%7.9/x86_64/kickstart%' ;" | su - postgres -c "psql foreman"

4. Run "pulpcore-manager analyze-publication" against the same with and without --tabular option.



Actual results:

# echo "select relative_path from katello_repositories where relative_path like '%7.9/x86_64/kickstart%' ;" | su - postgres -c "psql foreman"
                                        relative_path

Expected results:


* No such WARNINGS about AUTHENTICATION_BACKENDS

* --tabular should work on RHEL 8.6 as well ( as it's the latest baseos of satellite 6.12 )


Additional info:


* This is the default config that comes with Sat 6.12 and it indeed does not have those AUTHENTICATION_BACKENDS that pulp is asking:

# grep AUTHENTICATION_BACKENDS /etc/pulp/settings.py 
AUTHENTICATION_BACKENDS = ['pulpcore.app.authentication.PulpNoCreateRemoteUserBackend']



* RHEL 8 ships python3-prettytable-0.7.2-14.el8.noarch but the prettytable module that comes along with it is for python 3.6 and pulp uses python 3.9. That's why the error.
