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.
