I’ve tried to find a good explanation or how to fix this, but kinda lost.
Download (curl) error for 'http://www.opensuse-education.org/download/repo/1.0/11.1/content':
Error code: Unrecognized error
Error message: Maximum (3) redirects followed
They are different repos. The one from openSUSE Education - News is an stable repo, is like an stable version of openSUSE where programs aren’t updated (only security fixes and major problems). The one from the OBS is the development repo, where packages are constantly updated (and so is less tested).
About the problem…
$ curl "http://www.opensuse-education.org/download/repo/1.0/11.1/content"

It’s an error on the server side, a recurrent redirection. Report it to openSUSE Education, but problably they already know and will be fixed shortly.
