[R-sig-Debian] Problems Updating R version on Debian testing

[Shannon Markiewicz]

I am trying to update R on debian testing and am getting the following 
error from the package manager.  Do I need to change the website link?  
Is there a new signature for the repository that is compliant?

W: GPG error: http://cloud.r-project.org/bin/linux/debian jessie-cran3/ 
Release: The following signatures were invalid: 
6212B7B7931C4BB16280BA1306F90DE5381BA480
E: The repository 'http://cloud.r-project.org/bin/linux/debian 
jessie-cran3/ Release' is not signed.
N: Updating from such a repository can't be done securely, and is 
therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user 
configuration details.

Thanks,

Shannon
