Issue with Debian 13 and Subscription-Manager

I tried to subscribe a Debian 13 server with foreman. The registration is working pretty fine. But If I do a apt-get update. All the repos getting ignored, with different error message. One error says the Missing Signed-By in the sources.list(5) for the Foreman repos. There are also some repos in between they a bringing a 404.

Do I need to conisder something special for Debian 13? what I did is downloading the Lifecycle Server certificate and adding it into the truststore and running the katello-rhsm-consumer script after installed subscription-manager.

Foreman and Proxy versions: 3.15.0

Foreman and Proxy plugin versions:
Katello: 4.17.0
Foreman-Tasks: 11.0.0
Foreman_Remote_Execution: 16.0.3

Distribution and version: Debian 13

What I saw in the RHSM Logs after I changed the log level to Debug is the error message: Could not find pulp signing-key in /etc/apt/trusted.gpg.d

Thank you.

Hi @ChrisRo0341

If you register a host running Debian or Ubuntu and you provide content from your Foreman+Katello, for example, the Client repository, then you must also provide the GPG key used by Pulp to sign the Release file. You should get the release file on FQDN/pub/pulp_deb_signing.key.

Please have a look at step 4: Registering hosts and setting up host integration - orcharhino documentation
