Can you tell me a few things about your plague server?

1) What version of yum is it running?
2) What version of yum-utils if any?
3) the output of:

rpm -qf /usr/lib/python2.3/site-packages/repomd/mdErrors.py
rpm -qf /usr/lib/python2.4/site-packages/repomd/mdErrors.py

4) Next, can you try:

python
>>> import repomd.mdErrors
>>> repomd.mdErrors.PackageSackError

5) Then try:

python
>>> import yum
>>> yum.Errors.PackageSackError


I think this is an issue of the yum depsolve stuff moving from yum-utils
to yum itself, we just need to figure out what the permutations are and
then work around them in the source.


Thanks,
Dan
