[Spacewalk-list] spacewalk client not seeing signed rpms, or Public key not installed error

[Janet Houser]

Unfortunately, this issue is intermittent and remains unsolved.  Some 
resigned rpms work, others don't. Communication on the client side 
appears to be the issue.  Perhaps this issue is related to using the 
postgres db.

Found a workaround:

On the spacewalk client, edit the file 
/etc/yum/pluginconf.d/rhnplugin.conf.  Add the name of your
personal spacewalk repository where various gpg signed rpm exist via an 
entry of the form:

[my-custom-spacewalk-channel]
gpgcheck = 0
