Can't login to container registry after fresh install

[UnixxSH]

Version
pulpcore: 3.54.1
container: 2.20.0
docker hub image: latest

Describe the bug
I've just initialized the docker image, set a password for admin account. I've created a container repository, and tried to login, but the following is returned by the podman cli:

Error: trying to reuse blob sha256:f82b800c4e07c93bbf3a96d8e5c3f80cb1983c1a63648ff85a16d3c42b9e012f at destination: pinging container registry localhost:8080: received unexpected HTTP status: 500 Internal Server Error

In container logs, the following is shown:

Traceback (most recent call last):

    self.initial(request, *args, **kwargs)

During handling of the above exception, another exception occurred:

To Reproduce
mkdir -p settings/certs pulp_storage pgsql containers
echo "CONTENT_ORIGIN='http://$(hostname):8080'" >> settings/settings.py
podman run --detach
--publish 8080:80
--name pulp
--volume "$(pwd)/settings":/etc/pulp:Z
--volume "$(pwd)/pulp_storage":/var/lib/pulp:Z
--volume "$(pwd)/pgsql":/var/lib/pgsql:Z
--volume "$(pwd)/containers":/var/lib/containers:Z
--device /dev/fuse
pulp/pulp
podman exec -it pulp bash -c 'pulpcore-manager reset-admin-password'
pip install pulp-cli[pygments]
pulp config create --username admin --base-url http://localhost:8080 --password
pulp container repository create --name test
podman login -u admin -p admin http://localhost:8080/test

Expected behavior
I'm supposed to be loggued to the registry. Unless I don't understand the documentation properly (I don't know why it is specified to use the port 24817 by the way). There are also dead links so I'm not sure what I did wrong.

It seems like you have encountered the same error as the user in https://discourse.pulpproject.org/t/pulp-standalone-container-docker-cant-pull-docker-images-through-pulp/1284.

Please, try carefully reading the documentation once again: https://pulpproject.org/pulp-oci-images/docs/admin/tutorials/quickstart/#podman-or-docker-compose. We explicitly mention that "the Pulp Container plugin requires key pair generation."

More and more users are having troubles to understand how to pre-configure a Pulp instance. @UnixxSH, what could we do better next time to prevent this from happening?

Closing due to inactivity.

Hi @lubosmj , sorry for the late reply, I don't know why I didn't received any notification until this issue is closed. I disabled token authentication, and it is now working.

Regarding your question

More and more users are having troubles to understand how to pre-configure a Pulp instance. @UnixxSH, what could we do better next time to prevent this from happening?

I honestly just should have read the documentation better.

Awesome! Have a wonderful day!
