Luis,
I just wanted to thank you for posting this script.
For the last couple of days, I've been puzzling thru any cobbler install on any main stream Linux distro. Your script was the first batch of set up instructions that actually worked as indicated. (And instructions incorporated in a set up script to boot!)
As it happens, I used Ubuntu 14.04; not 14.10. But it (not surprisingly) worked fine.
Thanks again for the post and the help.

Cheers... Mark

Hi - I've been trying to use the repo that is specified in this script, but it is now empty and fails:
