installing R in Ubuntu...issue

Question

I have attempted to install R on my Ubuntu 16.10 Yakkety.

I placed the following deb in my /etc/apt/sources.list file.

deb http://cran.ma.imperial.ac.uk/bin/linux/ubuntu yakkety main
universe restricted multiverse

However, after running sudo apt-get update, I get the following message, which I do not understand:

Fetched 102 kB in 6s (15.7 kB/s)

Has anyone come across this before, when installing R in Ubuntu 16.10?

You forget to import the pgp-key for this repository. Therefore the error reports.

To add the key run sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9 afterwards sudo apt update.

There is a lengthy explanation of how to add their repositories here: http://cran.ma.imperial.ac.uk/bin/linux/ubuntu/README

The line in your sources.list file should be:

deb https://cran.ma.imperial.ac.uk/bin/linux/ubuntu yakkety/

You do not need "main" or so.

And then, read the instructions for Secure APT on https://cran.r-project.org/bin/linux/ubuntu/. apt complains about not being able to authenticate the packages from the server.

Why don't you install directly using

sudo apt-get install r-base

Or download the deb from here

and install using gdebi

The Ubuntu repository does have R (as well as many, many packages like r-cran-spatial), but they are often not the newest versions. – user258532 Apr 18 '17 at 20:33
