[Spacewalk-list] file missing during kickstart?

[Jason Welsh]

 kickstart is going fine, until it gets to the
libxml2-python-2.6.26-2.1.2.8.x86_64.rpm

and then it errors with
the file libxml2-python-2.6.26-2.1.2.8.x86_64.rpm cannot be
opened. This is due to a missing file, a corrput package or corrupt
media. Please verify your installation source.

on the other console, I see

try 1-10 to retrieve
http://redhouse2/ks/dist/rhel-server-5.5/Server/libxml2-python-2.6.26-2.1.2.8.x86_64.rpm
but it cant..

I look in spacewalk under my channels and i see that file is there under
the packages, and the file
seems fine in the tree on my filesystem

[root at redhouse2 ~]# ls -al
/var/distro-trees/rhel-5.5-5-x86_64/Server/libxml2-python-2.6.26-2.1.2.8.x86_64.rpm

[root at redhouse2 ~]#

any ideas on how to fix this?

regards,
Jason
