Description of problem: Preupgrade tries to download all the packages needed for a successful upgrade to disk before rebooting to anaconda. Since preupgrade uses the original yum from the current installation and anaconda uses the new yum, it sometimes happens the two yum versions calculate a different set of packages for the upgrade and therefore some packages can be missing in preupgrade's directory on the disk. In such case anaconda should be able to download the missing packages from a standard mirror. The problem is anaconda does not set up the network, so the download fails and the upgrade can't proceed. In my case I was upgrading from F7 to Rawhide and the missing package was compat-expat1. Version-Release number of selected component (if applicable): I hit the bug on 2008-04-13, so I guess it was: anaconda-11.4.0.71-1 Steps to reproduce: Deleting an RPM from /var/cache/yum/anaconda-upgrade/packages before rebooting into the upgrade environment should do it.
Breaks a new feature in a pretty substantial way and I have a patch that at least should work locally, it just needs to be tested. So sticking on the blocker list.
And cleaned up the patch to where it's working and pushed to git.
This isn't in F9PR (anaconda-11.4.0.73) but should appear in the next anaconda build.
Confirmed fixed in anaconda-11.4.0.74. Yay!
