The problem may be with the mirrored server. If you are in Africa, it’s possible if not probable that the installer added this mirror in South Africa:
ftp://ftp.is.co.za/mirror/opensuse/opensuse/distribution/
The 10.3 repo works, but the 11.0 directory is not there. On the international mirrors list, I noticed there are some others shown for 11.0 but also don’t have this release. So, go to the list, find a location closest to you, click on Installation Repository. You should be taken to an http or ftp directory; the server domain names and top directory structure vary, but the repo itself will be under something like “/distribution/11.0/repo/oss/”. You’ll also want the “non-oss” repo; that’s where java, flash, i.e., the proprietary software, is stored. Here’s the list:
Mirrors Released Version - openSUSE
Bear in mind that the geographically closest is not always the fastest. More important is the number of hops, the servers routed through, the repo server’s bandwidth and current load.
Once you find the repo’s, highlight the entire url in the browser address bar, right-click and copy, run YaST Software Repositories, click Add, click Next, Paste into the url field, click Next. You should see the repo added to the list. Be sure the Enabled box lower-left is checked, and the Automatically Refresh is not (these repo’s don’t change).
You will probably also want the Packman and VLC repo’s added to get the proprietary multimedia pieces that cannot be bundled with openSUSE. There is a one-click install for this, but AFAIK it adds Packman’s Belgian mirror; where you are located you might want a different mirror. They are all listed here:
Additional YaST Package Repositories - openSUSE
You can still use the one-click install though, after setting up the repo’s like above. Just click on Customize and de-select the mirror shown, and proceed to install.
