I ran preupgrade on an up-to-the-minute-updated F11 system. Everything seemed to proceed normally until I "rebooted." Even then it looked good until an error message came up: Upgrade root not found The root for the previously installed system was not found. Exit Installer [Button] Don't know what that means. Why does it want the "root" for the previous system? The system restarted F-11 after I clicked "Exit Installer." It appears that I have all the F-12 files downloaded somewhere in this box, I haven't looked, but it seems there ought to be a way to finish. Now I have looked and all the files are there, more than a gig of rpm's and I can continue to run preupgrade and it finds those downloaded files but still produces the same error. If I could repair whatever seems damaged it seems it ought to work?. What do I need to do now?
