Similar error after PackageKit is trying to update. Btw. it is clean install.
Before update, I was installing yum-fastestmirror and yum-presto.
PackageKit is 0.4.6.8 version.

  File "/usr/share/PackageKit/helpers/yum/yumBackend.py", line 2534, in _getPackage
    sections = name.rsplit('-', 2)
AttributeError: 'NoneType' object has no attribute 'rsplit'

OK, I see that error is because of presto plug-in.

You can't upgrade directly from F9 to F11... You have to do a clean install

The yum database changed format in F10.
