Created attachment 325758 [details] screenshot of fatal exception Description of problem: When trying to do the reboot after downloading and installing preupgrade, there is a fatal exception. I tried both methods described on http://howtoforge.com/how-to-upgrade-from-fedora-9-to-fedora-10-desktop-and-server and both show the same problem upon reboot attempt. See screenshot. Version-Release number of selected component (if applicable): from 9 to 10 using preupgrade How reproducible: Well, just try the two methods described on that website. Just try to reboot after preupgrade has run, or the wget method. Steps to Reproduce: 1. 2. 3. Actual results: fatal exception Expected results: for sure not fatal exceptions, but the end result should be bootable F10 installation. Additional info: Very frustrating. There should never be fatal exceptions upon boot. No, my hardware is NOT broken!
It's hard to say from the attached image - I'd need to see the whole traceback / crash dump log to be sure - but what's visible matches the problem in bug 473260. Does your Fedora 9 system use a swap file, by any chance?
Yes, it does. During the install from CD/DVD the installer crashed several times, so I couldn't set up a swap partition, although that is recommended. Later on on the IRC #fedora group someone recommended to simply set up a swap file instead.
This is bug 473260, then. The simplest workaround seems to be to edit /etc/fstab and comment out the line for your swap file. Then reboot into the upgrade. The upgrade should complete successfully, and then you can edit /etc/fstab again to restore your swap file. *** This bug has been marked as a duplicate of bug 473260 ***
I confirm that deleting the swap file entry in /etc/fstab allowed me to boot into F10. This is the solution the original poster Alexej Kutznetsov in 473260 found.
