RHEL6 Installation Problems


We have installed a new RHEL6 server and when trying to install Interworx, the installer stalls at Interworx-CP installation.

First off, at the beginning of the installation process, we can see these errors:

STATUS: Importing RPM GPG keys
error: http://updates.interworx.com/iworx/RPM-GPG-KEY-NEXCESS: key 1 import failed.
error: http://updates.interworx.com/redhat/9/en/os/i386/RPM-GPG-KEY: key 1 import failed.

We have verified and the keys are available we can see them in a browser or such...

Then, in the QMail installation section:

Error: Package: php-iworx-5.2.14-4.rhe6x.iworx.x86_64 (interworx-cp-rhe6x)
Requires: libc-client.so.2007()(64bit)

Then, in the Interworx-CP section:

Error: Package: interworx-4.7.2-358.iworx.noarch (interworx-cp-noarch)
Requires: netpbm-devel
Error: Package: php-iworx-5.2.14-4.rhe6x.iworx.x86_64 (interworx-cp-rhe6x)
Requires: libc-client.so.2007()(64bit)
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
ERROR: InterWorx-CP could not be installed.
ERROR: YUM may have given some reasonable errors and
ERROR: you can try re-running the installer as it may
ERROR: just be a network and/or update server problem
ERROR: If after re-running the installer you still
ERROR: receive an error please open a support ticket at:

It seems there are some things not working on RHEL6.  The system is updated to the most recent packages.

Thanks for any help!

We’ll probably need to login to the server to investigate these issues. You can provide that info via the support ticket, and when we know how to fix it, we’ll post here so everyone gets the benefit of it being on the forums!


As Paul replied to us, here is the answer :


I believe you need to install the “optional” redhat repository. Can you try doing that by running:

rhn-channel -a -c rhel-x86_64-server-optional-6

you’ll have to enter your redhat network user/pass


Thanks Paul,

Excellent! This did the trick! Sorry about this one, we only have CentOS servers but for this one we needed new versions of some software (like QT and such) so we decided to go with RHEL for the first time. We are not yet used to all the fancy differences between CentOS and RHEL…

Thanks a lot! Your support is up to the challenge.
