Hello @mark
I had that happen and I had to rerun the configuration script. Can you post a copy of your answer file and delete or hide all passwords IPs and URLs? It is related to your SSL configuraiton.
BTW, post the content of your '/etc/yum.repos.d/kaltura.repo' file so I can see were you are pulling the RPMs from. Sometimes you get old files or other don't update cause the main server has not updated with the latest RPMs. Some of this was mention by @jess in this thread.
