I've recently installed Fedora Core and have just learnt about Yum (version 2.0.4). When I tried yum list available I was sent repeated "retrygrab() failed for:" messages and then "[Errno 4] IOError: HTTP Error 404: Not Found:" I checked the Yum archives and one user had apparently fixed a "retrygrab() failed" response by replacing an "http" with a "ftp" somewhere in his 'yum.conf' file. But I could not find a similar server, so I wouldn't know what server to change. Is this a common problem with Yum or is there more lilely something wrong with my version? -- Dr Blair M.
