I have USA mirror ftp://mirror.colorado.edu/pub/opensuse/update/10.3 working as an update site in 10.3B3 in "Smart".

I have been able to update all except the latest "/libzypp-3.22.1-8.x86_64.rpm" which it can't open.

I named it "updatecolo" to distinguish among all the other international mirrors that I have tried.

Oh yes, there is a kernel update (-12) there too.

Have fun...
