Subscription-manager command not found

I’m using a Foreman server with Katello, I’m currently on a Debian 11 client that I want to add on my Foreman server (CentOS Stream 8) but it doesnt work

Expected outcome:
Client is synchronised with Foreman server

Foreman and Proxy versions:
Foreman 3.9

Foreman and Proxy plugin versions:

Distribution and version:
CentOS Stream 8

Other relevant data:
I typed these commands :
apt-get install -y python3-subscription-manager
apt-get install -y python3-katello-host-tools*
apt-get install -y katello-host-tools-tracer

But when I type : subscription-manager register --org=“Default_Organization” --activationkey=“Debian 11”

I just get a bash: subscription-manager : command not found

Hi @Hugo.G ,
please have a look here: Subscription Manager for Debian & Ubuntu on
