Hello, I was following the instructions at https://cran.r-project.org/bin/linux/ubuntu/#secure-apt but encountered this message upon apt-get update: GPG error: http://cran.rstudio.com trusty/ Release: The following signatures were invalid: KEYEXPIRED... And then the following on apt-get install: WARNING: The following packages cannot be authenticated! Investigating a little, it looks like Michael Rutter's key expired today: http://keyserver.ubuntu.com:11371/pks/lookup?op=vindex&fingerprint=on&search=0x51716619E084DAB9 I thought it'd be better etiquette to post here before emailing Dr. Rutter directly, in case I've overlooked something. All the best, John Milner
