Does anyone know how to address this problem? My laptop battery died while upgrading using Pre-upgrade. It was not connected. So what should I do when I switch it on?

Cross your fingers, and hope that your RPM database isn't fscked.

Any suggestions?

Nope, you'll be flying by the seat of your pants. It's anyone's guess what state your system will be in. Chances are fairly good that you'll be able to boot, at least in run level 1, so you can get a shell prompt.

Presuming that you can get a shell, the next step would be to assess the damage to your RPM database. Presuming that rpm --rebuilddb survives, the next step would be to run "rpm -q -a", and see what you've got.

When rpm goes down in a middle of updates, the most likely result is that the rpm database will list both the old and the new version of each package, and you'll need to compile a list of them all, and manually remove the old version of each package.

Been there, done that. It's not fun, but the only other option is to salvage the data, reformat, and reinstall.

Once you manage to put your rpm database in a sane state, the next best thing to do is to forget preupgrade, and run F11's installer, which will clean up and finish the install.

I wonder if preupgrade keeps a log file of what it did up to the point your battery died? I also wonder if it built a kickstart file and saved to it incrementally? How about terminal output, was that saved anywhere? I've never done a preupgrade, my preference is to do fresh installs and then copy over the important data bits from my network. But I presume it logs its progress somewhere? Or not? What I'm hoping for is that there is a file somewhere that can be fed back to preupgrade which says: "I was at this point a when the system died. I can resume processing from here."
