I have Fedora core 5, updated recently. Today, yum update was failing for me, saying: No module named cElementTree After a bit of searching I found http://effbot.org/downloads/#cElementTree Unpack, then say: # python setup.py install This helped yum get further, failing with: cannot import name iterparse It is here: http://effbot.org/downloads/#elementtree Again, unpack and say: # python setup.py install Was there a better way to fix this? My yum.conf is a bit convoluted, maybe that caused the problem. cheers -- Rick
