Red Hat Bugzilla – Bug 437528
yum seems to be repeatedly re-downloading packages for no apparent good reason
Last modified: 2014-01-21 18:02:05 EST
As part of a pungi compose, I'm pointing at a local mirror. When I get to the download phase, yum tries downloading the package numerous times, and eventually fails. If I use urlgrabber directly it works the first time.

Mirror: my home InstantMirror * 20080314 rawhide anaconda fails like Jesse's example above. * Meanwhile, livecd-creator downloading the same RPM from the same mirror succeeds. Both use yum, yet one succeeds and the other consistently fails. When it fails, it is as if it gives up on downloading part-way and tries again.
It looks like it's downloading exactly 1.1MB of each file and then dying, this is more than a little suspicious. Does anaconda succeed if it isn't using InstantMirror? It's not obvious it's an anaconda problem but it really doesn't look like a yum problem, and urlgrabber hasn't changed in quite a while now.
Anaconda failed in a similar way on a public mirror on Friday for me too. Back to the InstantMirror case, anaconda in F-8 seem sot have no problem installing from InstantMirror. Also, anaconda F-9 works if the InstantMirror RPMS are pre-populated, so the server isn't downloading at the same time it is serving to the client. Are you sure nothing related to HTTP header handling changed? It is telling that livecd-creator and yum themselves have no problem on the very same RPMS that anaconda and pungi seem to have trouble.
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Is this still happening?
I can't say that I've seen it. The circumstances around getting to this error state are usually pretty complicated. However from my end feel free to close this, I'll re-open if it's happening again and there is something to test against.
