URLGrabError exception when running preupgrade (F14 -> F15a, post boot)
Last modified: 2013-07-03 22:26:47 EDT
Description of problem: After running preupgrade and rebooting the host, the upgrade does not run. It exits with an exception (see full backtrace in additional info): mirror.py:283:_get_mirror:URLGrabError: [Errno 256] No more mirrors to try. A nicer exit message would benefit the poor user, who is clueless as to why his upgrade did not work. One cannot see that it actually failed, only when looking at /var/log/messages: Mar 13 18:07:08 ykaul preupgrade-gtk.py: abrt: detected unhandled Python exception in /usr/share/preupgrade/preupgrade-gtk.py (Note: tested from within RH office network, so one would assume mirrors should work well. Guess they didn't). Version-Release number of selected component (if applicable): preupgrade-1.1.8-1.fc14.noarch How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: mirror.py:283:_get_mirror:URLGrabError: [Errno 256] No more mirrors to try.

I had the same error here. But it seems to be fixed with the latest build. preupgrade-1.1.9-1.fc14 worked just fine. (might be by accident, though)
I had the same problem, and 1.1.9 also fixed it. Closing bug... - Mike
