Retreiving packages for my i386 system running RHL7, using the GUI up2date 2.0.6-1. Traceback (innermost last): File "/usr/share/rhn/up2date/gui.py", line 350, in doRetrieval self.setProgress) File "/usr/share/rhn/up2date/up2date.py", line 527, in getPackage raise CommunicationError(f.faultString) up2date.CommunicationError: Error communicating with server. The message was: Invalid Architecture and OS release combination
I also have this problem. I found that it seems to occur when "Retreive source RPM along with binary package." is checked in rhn configuration.
this has been corrected in an errata release of update agent due out this week.
