[Spacewalk-list] Uninstall errors

[Per Qvindesland]

Hello List

I am trying to un-install spacewalk to then re-install it again, I ran yum
erase spacewalk-* which seems to do most of the trick, but i then get a few
errors:
error reading information on service taskomatic: No such file or directory
  Erasing   : spacewalk-backend-config-fil ####################### [21/39]
error: %preun(spacewalk-java-0.4.16-1.el5.noarch) scriptlet failed, exit
status 1
error reading information on service satellite-httpd: No such file or
directory
  Erasing   : NPalert                      ####################### [36/39]
error: %preun(spacewalk-config-0.4.24-1.el5.noarch) scriptlet failed, exit
status 1
Does anyone know how I can remove these packages, been trying to google but
I come up clean, I also did yum remove yum rhel-instnum, is there anything
else that I need to remember to remove?

Kind regards
