Hello,

Can you tell me which morpheus-node package version you are installing? You can get it by running

rpm -q morpheus-node

I can try to reproduce this on RHEL 7.

3

Yes, sure. here is morpheus-node-3.2.10-1.el7.x86_64

Morpheus is V 5.5.3.

@alipscombe will be great if you can also provide some suggestions.

Thanks,
Aung

hello @aungkyawthu It appears that your deployment is failing when attempting to enable the rhel-7-server-rhui-extras-rpms repository on the KVM host.

Please can you manually execute sudo yum-config-manager --enable rhel-7-server-rhui-extras-rpms on the host. can you also share the version of RHEL 7 you are using.

Hello @aungkyawthu

The rhel-7-server-rhui-extras-rpms repository requires an RHUA instance running within your infrastructure.

When registering the RHEL 7 host with subscription-manager you need to pass in the argument --type=rhui command example: subscription-manager register --type=rhui --username <admin-example> --password <secret>

I believe the rhel-7-server-rhui-extras-rpms is a copy of the rhel-7-server-extras-rpms repository.

Please can you raise a case with the product support team? So that we can investigate further.

Thanks
Adam
