Also you need to add the gpg key to spacewalk and add it to your activation key you are registering against to prevent it from happening again. <div class="gmail_quote">On Aug 27, 2012 4:59 PM, "Anton Pritchard-Meaker" <<a href="mailto:anton.pritchard-meaker@kit-digital.com">anton.pritchard-meaker@kit-digital.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div lang="EN-GB" link="blue" vlink="purple"> <div> Try getting the GPG key from your spacewalk server and importing it: cd /tmp && wget <a href="http://spacewalkserver.com/pub/RPM-GPG-KEY-redhat-release" target="_blank"> http://spacewalkserver.com/pub/RPM-GPG-KEY-redhat-release</a> rpm --import /tmp/RPM-GPG-KEY-redhat-release Then try the yum command again.

Here is the message that I got: warning: rpmts_HdrFromFdno: Header V4 DSA signature: NOKEY, key ID 863a853d Public key for rhnlib-2.5.51-1.el5.noarch.rpm is not installed I’ve tried searching a bit for how to handle this error. So far nothing obvious is hitting me for this error related to Spacewalk clients. Anyone have any idea what I need to do to clean this up? I already tried yum clean all. That made no difference. I suppose I could try excluding that one package and see what happens. Here’s the repolist info from the client: yum repolist -v Loading "priorities" plugin Loading "rhnplugin" plugin Loading "security" plugin Config time: 0.045 Looking for repo options for [rhel-x86_64-server-5] Looking for repo options for [rhel-x86_64-server-supplementary-5] Looking for repo options for [spacewalk-5-x86_64] Yum Version: 3.2.22 Repo-id : rhel-x86_64-server-5 Repo-name : RHEL 5 (64-bit core server) Repo-status : enabled: Repo-updated: Fri Aug 24 04:11:50 2012 Repo-pkgs : 3,388 Repo-size : 3.7 G Repo-baseurl: <a href="http://spacewalk/XMLRPC/GET-REQ/rhel-x86_64-server-5" target="_blank"> http://spacewalk/XMLRPC/GET-REQ/rhel-x86_64-server-5</a> Repo-id : rhel-x86_64-server-supplementary-5 Repo-name : RHEL Supplementary (v.5) Repo-status : enabled: Repo-updated: Sat Aug 25 05:42:37 2012 Repo-pkgs : 120 Repo-size : 1.0 G Repo-baseurl: <a href="http://spacewalk/XMLRPC/GET-REQ/rhel-x86_64-server-supplementary-5" target="_blank"> http://spacewalk/XMLRPC/GET-REQ/rhel-x86_64-server-supplementary-5</a> Repo-id : spacewalk-5-x86_64 Repo-name : Spacewalk Infrastructure RHEL 5 x86_64 Repo-status : enabled: Repo-updated: Wed Aug 22 15:51:46 2012 Repo-pkgs : 206 Repo-size : 132 M Repo-baseurl: <a href="http://spacewalk" target="_blank"> http://spacewalk</a> /XMLRPC/GET-REQ/spacewalk-5-x86_64 repolist: 3,714 Robert Boyd Senior Systems Engineer Phone: <a href="tel:919-645-2972" value="+19196452972" target="_blank">919-645-2972</a> Mobile: <a href="tel:919-306-4681" value="+19193064681" target="_blank">919-306-4681</a> Peoplefluent 434 Fayetteville Street Raleigh, NC 27601 <a href="mailto:michael.dileonardo@peoplefluent.com" target="_blank">robert.boyd@peoplefluent.com</a> <table border="0" cellspacing="8" cellpadding="0"> <tbody> <tr> <td style="padding:0cm 0cm 0cm 0cm"> <img border="0" width="179" height="65" src="cid:image001.png@01CD849E.98421820" alt="Description: Description: Description: cid:image001.png@01CC344B.23823870"> </td> <td style="padding:0cm 0cm 0cm 0cm"> </td> </tr> </tbody> </table> This email message is for the sole use of the intended recipient(s) and may contain confidential information.
