pulled x86-64 netboot iso image from download.fedora.redhat.com; default partitioning setup (sda1 is NTFS, used the rest for Linux), static IP setup, de-selected Office Applications in the software install screen. In the original (text-mode) dialog asking for the URL of the package repo, I got it wrong, and corrected it when the GUI mode installer said it couldn't find the right repodata.xml, which it then found and proceeded to the package listing bits.
Created attachment 305949 [details] anaconda debug log of traceback
Tried again, giving the correct URL the first time around, no change in the traceback.
false alarm, i386 media apparently, trying to install from x86-64 repos
