Hi Seth, I've been experiencing a strange effect on FC3 with yum-2.1.11-3 from the Install DVD without being able to find the cause until now. The command 'yum check-update' shows packages for update, a subsequent 'yum update' does nothing. Attempts to specify the package more exactly up to using version, architechture etc. help *sporadically*. Since this is intermittent, I haven't resorted to 'yum -d 10 ...' yet. Yesterday I saw got a 404-Not found Errror as well, and when I tried again, the update wasn't listed. I reduced my mirrorlist to one mirror, the updates were not listed. Today I saw *all* of the affected updates, and 'yum update' got them all, the release, version, etc. are *exactly* what I saw yesterday. I think: - the original 'yum check-update' got the repodata from the *primary* mirror. - when yum actually tried to retrieve the new packages, it couldn't reach the primary mirror, and tried one or more secondary mirrors, and reached one which hadn't yet synced. - and today the mirror I left active has synced from the primary. This is not really a huge problem, but might worry people until they realise what's going on - I thought yum wasn't working correctly. Maybe a message might help, assuming there's a way to catch the problem: "unable to retrieve package xyz, repo=abc, metadata from <timestamp>" or maybe it's one for the FAQ. Fred.
