My installation notes tell me that the Fedora extras repository is enabled by default which I take to mean that it is on my computer or on the cd's I loaded it from ?.Gnuchess is included in the list of extra's detailed also in these notes. But entering in root"yum install gnuchess" only returns " Cannot find a valid baseurl for repo: updates-released " So where am I clanging please, Regards all, Harry.
