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:

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
