When I run yum update or yum install, I receive the following error:

Traceback (most recent call last):
  File "/bin/yum", line 29, in <module>

How can I fix this?

The solution to this problem was to simply run either:

yum clean all


yum clean metadata

After running this I was able to yum update without problem.
