The arch of the release of Fedora you are upgrading to appears to be i586 which does not match your previously installed arch of i686. This is likely to not succeed. Are you sure you wish to continue the upgrade process?" Answer "No" to abort process.
It's odd enough that the installer is guessing - "the release of Fedora you are upgrading to appears to be i586" - that's not instilling much confidence is this already! :) To top that, "This is likely to not succeed."
Anyone care to enlighten me as to will, most assuredly, succeed. That's what I would rather use....
The message is bogos and should be removed to avoid confusing users. Please file a bug.
No, this particular instance of the message is bogus. The message itself serves a very important role: preventing people from trying to upgrade an x86-64 install with an i586 tree, for instance.
Anyway what release is this? This should have been fixed way back in the end of March.
