Description of Problem

After registering a CentOS Linux 7 system to production Insights the system is listed multiple times in the Host Based Inventory. Each of the inventory items has a different UUID. The system then cannot be converted using the conversion task in Insights.

How reproducible

Seems like always. I tried it with a CentOS Linux 7 system deployed using two different provisioners (1minutetip and testing-farm). The issue manifested in both cases.

Steps to Reproduce

1. Get a CentOS Linux 7 system
2. Run the following commands to get the system registered to production Insights

   sed -i 's/^mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
   sed -i 's|#baseurl=http://mirror.centos.org|baseurl=https://vault.centos.org|g' /etc/yum.repos.d/CentOS-*
   curl -o /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release https://www.redhat.com/security/data/fd431d51.txt
   curl -o /etc/yum.repos.d/client-tools-for-rhel-7-server.repo https://ftp.redhat.com/redhat/client-tools/client-tools-for-rhel-7-server.repo
   yum install -y subscription-manager subscription-manager-rhsm-certificates insights-client rhc rhc-worker-script
   rhc connect -a <key> -o <org>
   

3. You'll see no errors or warnings on the CLI

Actual Behavior

The registered system is listed twice or thrice in the Inventory, with different UUIDs. The OS of the first one is "CentOS Linux 7.9" but is not connected to RHC, the OS of the others is "Not available" but they are connected to RHC. With that, I cannot run the conversion task on the system. See attached screenshots.

Expected Behavior

The system is just once in the Inventory and I can run the conversion task on it.

Business Impact / Additional info

Customers facing this issue won't able to convert their systems to RHEL and support engineers will be burdened with cases.
