Created attachment 379468 [details] Preupgrade install info and stack trace. Description of problem: Towards the end of the preupgrade process going from F11 to F12 a Python exception occurred just after the "installing bootloader" part of the installation. Hardware: AMD Athlon64 i386 basearch machine running F11. All partitions on a hardware dm-raid device. Version-Release number of selected component (if applicable): I believe I was using preupgrade-1.1.3-1.fc11.noarch How reproducible: Install F11, run preupgrade to F12. Actual results: Preupgrade failure with "exception occurred". I was offered the opportunity to save the bug report, which I did by SCP to another machine. The installer then tried to exit but failed to do so, a blank screen remained showing only the mouse cursor with animated "work in progress" type blue dots around it in circles. Expected results: Full and safe upgrade to F12. Additional info: Preupgrade output and python stack trace attached.
This bug should be fixed in rawhide/F13 (anaconda-13.7-1) with commit 558abca4d3f6740eadba96ead716839440112759 which consolidates handling of grub target device names obtained in UI and in /etc/sysconfig/grub of upgraded system. The bug concerns particularly grub installed in mbr of dmraid device where "mapper/" part of its path was not removed after reading it from the config file. Thanks for the bug report.
