Description Yaniv Kaul 2011-03-14 03:07:00 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

Comment 1 Richard S. Hendershot 2011-03-20 02:03:18 EDT
this also happens with preupgrade-cli: preupgrade-1.1.8-1.fc14.noarch
Not tested from within RH network...   ;)

Comment 2 Christoph Höger 2011-03-28 10:09:46 EDT
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)
Comment 3 Michael J. Chudobiak 2011-06-24 14:42:51 EDT
I had the same problem, and 1.1.9 also fixed it.

Closing bug...
