    Hi there,

    I'm attempting to install cPanel on a RHEL6 box we have here; however when attempting to start the installation cPanel throws an error and the installation terminates:
    Code:
    [root@server home]# sh latest
    Verifying archive integrity... All good.

    Removing /root/installer.lock
    [root@server home]#
    My problem, however, is that as far as I can tell, the server already is registered with RHN. If I follow cPanel's instructions and run /usr/sbin/rhn_register, I get a warning that the server is already registered.

    If I run rhn_check I get a 0 exit code (suggesting RHN is configured correctly and working):
    Code:
    [root@server ~]# rhn_check -v
    [root@server ~]# echo $?
    0
    Has anyone got any idea what might be wrong?

    Hello :)

    There is an additional step to take when installing cPanel on RHEL. Before you install cPanel & WHM on a Red Hat Enterprise Linux v.6 server, you must subscribe the server to the Red Hat Enterprise Linux 6 Server - Optional (RPMs) channel. To subscribe to the RHEL Server - Optional (RPMs) channel, run the following command:

    Code:
    # subscription-manager repos --enable rhel-6-server-optional-rpms
    This is documented at:

    cPanel Installation - Configuring OS

    If the issue persists after following this step, please provide us with the output of the following command:

    Code:
    # yum check-update
    Thank you.

    Just thought I'd post an update in case anyone has the same problem and stumbles across this thread: The problem ended up being that we had the RPMs for subscription-manager installed; but it wasn't configured. This is because we were in fact using Satellite. So, as far as I can tell, cPanel noted the subscription-manager RPM was installed, and made an assumption we weren't using Satellite, which wasn't the case.

    So, the fix was simply just to 'yum remove subscription-manager'
