R help - May 2009 - Installing R on Ubuntu 8.10

Hi,

I am trying to install R on Ubuntu 8.10. I have added this line:

deb http://cran.at.r-project.org/bin/linux/ubuntu intrepid/

in my /etc/apt/sources.list file. However when I "Reload", I get the
following error message:
W: GPG error: http://cran.at.r-project.org intrepid/ Release: The
following signatures couldn't be verified because the public key is
not available: NO_PUBKEY D67FC6EAE2A11821

I have tried different mirror sites, but the result is the same. There
is nothing written about public keys on the download page:
http://cran.at.r-project.org/

Then, I have tried (after I added the line to the
/etc/apt/sources/list file) not pressing "Reload", but
"Close", and I
have written in the console:
sudo apt-get update

but I received similar message again:
....
Reading package lists... Done
W: GPG error: http://cran.rakanu.com intrepid/ Release: The following
signatures couldn't be verified because the public key is not
available: NO_PUBKEY D67FC6EAE2A11821
W: You may want to run apt-get update to correct these problems

Do you know what the problem is, and what should I do? Thanks in advance.

Maria

Maria,

Go to the CRAN website (or your preferred mirror), select Linux under the
download and install section, then select Ubuntu, and read what it says about
installation.
