Just tried (and failed) update f15->f16. Using dvd (most reliable method). Went fine until I hit an error, trying to update ipython. At this point, anaconda just quit. No hints given what the issue was. No offer to try to report the error. It mentioned that it _might_ be caused by a problem reading the media. Switch consoles, I saw no hint of an I/O error. My guess is it might have been a cpio error because I had a newer ipython installed via easy_install. After trying various strategies to rescue, I gave up and did clean install. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
