Weird livecd failure

[James Heather]

Can anyone explain this? I can provide more details if relevant, but
it's running livecd-creator on a kickstart file that's been working up
to now. There doesn't seem to be enough info at the crucial point where
the error occurs.

This is a fully up-to-date F17 machine.

Hmm. Well, it turns out it was a URL for freshrpms that no longer
exists. But I can't say the error message was particularly helpful. It
did tell me it couldn't 'download or revert' repomd.xml, but it didn't
tell me which repository. (I'm not quite sure what reverting means in
this context.)

Particularly that would be a good thing to actually fail, and report the
exact repository that was unable to be reached or the repomd to be
retrieved anyways. Got any patches?
