There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

/usr/lib64/librpm.so.2: file too short

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.7.1 (r271:86832, Apr 12 2011, 16:15:16)
[GCC 4.6.0 20110331 (Red Hat 4.6.0-2)]

If you cannot solve this problem yourself, please go to
the yum faq at:

What exactly are you trying to do here?

Are you trying to upgrade fedora from one major release to another ? e.g. Fedora 15 to 16

Trying to upgrade to F16 from to F15

??? upgrade form 16 to the older 15 ????

or is that a typo ?

If 15 to 16
it looks like you change the version of python
yum REQUIRES the SPECIFIC version that is in the fedora updates repo

however seeing as SO MANY things have changed in 16 a fresh clean install is recomended

reformat to ext4 and install 16 on a clean drive .


for every fedora upgrade PREPARE for a new clean install
try the preuprgaed ( it is getting better) but expect to do a clean install .

I had the same problem. I had to use a new disc and do a fresh install.

Even If you are trying to downgrade your operating system for some reason(which has to be pretty good) , you should go for a fresh install as suggested by John.
