Description of problem: I tried to upgrade F16 i686 with F17 Alpha DVD x86_64. I wanted to check whether bug 735060 is resolved. However, to my surprise, anaconda allowed me to perform the upgrade, no warning/error message poped up. I don't believe cross-arch upgrade is supported, therefore it should not be made possible. The upgrade was really fast (probably just a few packages were installed) and at the end I was presented with an error about kernel packages (no_kernel.png). After hitting OK, the "Bootloader" dialog stayed open, even though anaconda switched to final screen (reboot.png). "Reboot" button was not clickable and I had to hard-reset. I believe that is another error - if there is an error dialog during "installing bootloader" phase, the original dialog stays displayed. After reboot, I booted again into Fedora 16 (the graphics and most of the applications seem to be fc16), but e.g. /etc/fedora-release says Fedora 17. Version-Release number of selected component (if applicable): F17 Alpha anaconda 17.11 How reproducible: probably 100% Steps to Reproduce: 1. install F16 i686 2. upgrade from F17 Alpha x86_64 3. Actual results: no error dialog Expected results: error dialog Additional info: Proposing as F17 Beta blocker due to criterion: "The installer must be able to successfully complete an upgrade installation from a clean, fully updated default installation (from any official install medium) of the previous stable Fedora release, either via preupgrade or by booting to the installer manually. The upgraded system must meet all release criteria" https://fedoraproject.org/wiki/Fedora_17_Beta_Release_Criteria The upgraded system clearly does not meet criteria. It's probably half-broken.

This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '17'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 17's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 17 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 17's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Anaconda no longer performs upgrades, but the same problem affects fedup. Reported as bug 981180.
