Hi, I am using Fedora Core release 4 (Stentz) Kernel 2.6.11-1.1369_FC4 on an i686. I have previously been using Yum Extender 0.44 - Build : 4, until recently I keep encountering the following error. When I launch the application, I see in the Output view the following message: Mirrordetection : best Cannot open/read repomd.xml file for repository: nrpms failure: repodata/repomd.xml from nrpms: [Errno 256] No more mirrors to try. It also display an Error dialogue box stating: Error in loading repository data failure: repodata/repomd.xml from nrpms: [Errno 256] No more mirrors to try. What happened? and what should I do? I have tried to reset repository cache but still got the same problem. I wish to update my system to use FC5 and also update other applications like OpenOffice. Please assist. Thanks!
