all these symptoms sound like your upgrade went horribly wrong. I've seen
preupgrade mash up a box by half upgrading like that. It's the main reason
I don't think preupgrade is actually safe to use yet.

Preupgrade's process is to depsolve - using the same method anaconda does, download the pkgs it solves out. Put them in a cachedir. Download a kernel and an initrd, Setup a ks.cfg. then reboot the machine and allow anaconda to do the install.

Specific issues we've had with preupgrade are related to not being able to find a mirror and/or not being able to get pkgs. However, once the pkgs are downloaded and the system reboots it is all in Anaconda's hands.

The case of yum being 'partially' upgraded came from us having a newer yum in f10+updates than was in F11. This was documented here:


and the fix provided for it works to get you to update properly.

now, since farkas just mentioned that he didn't actually run preupgrade when things went badly then it suggests to me that preupgrade is probably not to blame.

Alan, if you can describe the situation where preupgrade munged up a system, I'd like to take a look.
