Alternatives to add key

SECURE APT

The Ubuntu archives on CRAN are signed with the key of "Michael Rutter
<marutter@gmail.com>" with key ID E084DAB9.  To add the key to your
system with one command use (thanks to Brett Presnell for the tip):

   sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9

An alternate method can be used by retriving the key with

   gpg --keyserver keyserver.ubuntu.com --recv-key E084DAB9

and then feed it to apt-key with

   gpg -a --export E084DAB9 | sudo apt-key add -
