I am very new to Linux so I probably am doing something stupid but I cannot seem to update to R 2.15
Using Ubuntu 12.02 Precise Penguin I realise that debian packages are not updated regularly so I tried to follow the insructions at the R-site So far, I have modified /etc/apt/sources.list to read ## R CRAN added 2012-06-12 deb http://probability.ca/cran/bin/linux/debian squeeze-cran/ Issued command: sudo apt-get update RESULT W: GPG error: http://probability.ca squeeze-cran/ Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 06F90DE5381BA480 Ubuntu seems to have happily run through all the other updates with no problem Any suggestions?
