F8->F9 preupgrade hung at "downloading installer metadata..."

[Chris Bredesen]

This is the third time I've run up to this point, and it's gone for as 
long as 15-20min without moving.  Here's the console output thus far:

$ sudo preupgrade
No package matched to remove
Traceback (most recent call last):
   File "/usr/share/preupgrade/preupgrade-gtk.py", line 198, in 
on_assistant_apply
     self._do_main()
   File "/usr/share/preupgrade/preupgrade-gtk.py", line 206, in _do_main
     self.main_preupgrade()
   File "/usr/share/preupgrade/preupgrade-gtk.py", line 349, in 
main_preupgrade
     self.pu.retrieve_treeinfo()
   File "/usr/lib/python2.5/site-packages/preupgrade/__init__.py", line 
390, in retrieve_treeinfo
     raise PUError, "Cannot find any kernel/initrd section for this arch 
in treeinfo"
preupgrade.PUError: Cannot find any kernel/initrd section for this arch 
in treeinfo

Anyone else seeing this?  Are the mirrors just overloaded?

Thanks,

Chris
