Modern versions of rhncfg-actions can call the getServerlURL() method in the rhn-client-tools up2date_client/config.py. That method does not exist prior to rhn-client-tools-1.3.7-1, so rhncfg-actions should require that version or newer, not just any version.
It's not just rhncfg-actions, there's some common code that can call that function too, so I made the dependency be on rhncfg. Committed to Spacewalk master: e0eb1fbccebf85aa0b84cb0443d194c78daf12c2
New commit, old commit can be ignored: 212e7da52fdf2a1c61cb802ef6db069299ad9fe6 I now specify the correct version we need to include for RHEL 5 and 6. For anything else we punt and just revert to old behavior. I didn't make it clear in comment 0, but this is a problem currently. If you have sufficiently old rhn-client-tools then you will get an error when using rhncfg.
Marking bug as ON_QA since tonight's build of Spacewalk nightly is a release candidate for Spacewalk 1.9.
Spacewalk 1.9 has been released. https://fedorahosted.org/spacewalk/wiki/ReleaseNotes19
The RHEL 5 if statement was not correct, so we do not yet guarantee that the right version of rhn-client-tools is installed on RHEL 5. Re-opening, fixing with this commit to Spacewalk master: 939ccf905ab1bf2d4a42c640aed162c2f19b68ab
Switching MODIFIED Spacewalk bugs to ON_QA before 2.1 release.
