I'm experiencing the same problem in Oneiric. Deleting /etc/apt/apt.conf.d/20packagekit made the error message go away.
I did have packagekit-backend-aptcc installed. I'm going to reinstall packagekit and see if that fixes things... (reinstalling via "apt-get install --reinstall") Hmm.. It didn't re-create the /etc/apt/apt.conf.d/20packagekit file. (apt-get purge packagekit; apt-get install packagekit) Now it's back.
