cannot install swift using packstack

[Dafna Ron]

using packstack, we keep failing to install swift.
if I use external data servers than the installation just gets stuck forever without exiting.
to see what is wrong I changed the answer file to install everything locally and we are getting package key error in the log even though the packages are already installed.

[root@nott-vdsa ~]# rpm -qa |grep swift

This is a problem with your yum repos. Nothing can be done on Packstack side.
