linux r apt

I am on R version 2.13 and would like to update to a newer version in order to use some packages that depend on R>= 2.14.

I have the line to my sources.list file as found described here. I then navigate to the terminal and type:

sudo apt-get update

and get the following error when trying to update R on the CRAN mirror closest to me:

Reading package lists... Done

W: GPG error: http://lib.stat.cmu.edu oneiric/ Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 51716619E084DAB9

Any idea how to debug this error?

The simplest solution that worked for me was from Emre Sahin in this thread:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9
