Outdated r-base-core when installing on Ubuntu 14.04

Since 14.04 is the Long Term Support version, which also is used by
Linux Mint, it's not really outdated, and a lot of folk, myself
included, use that stream (my machine says Linux Mint 17.1, but I think
that is simply the splash screen). I say stream, because the kernel and
other infrastructure are  being updated, though probably not to the
level Dirk prefers, and I do use other distros for some work. My own
sources.list includes

deb http://cran.stat.sfu.ca/bin/linux/ubuntu trusty/

and R updated fine to 3.2.4 last week with a typical automated prompt
that there were updates available.

So maybe Matt's problem is something else. This was the first time I'd
read about crouton (I run regular Linux distros). Is that getting in the
way somehow?

| 
| 2) Add Michael Rutter's key with
| 
| sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9
| 
| 3) Update sources and attempt to install R:
| 
| sudo apt-get update
| sudo apt-get install r-base
| 
| Here is the full text of the error I get:

Then something is wrong with your apt entries. Check and double check.

I run wily here (because why would I want to be on an almost two year old
OS?) and it looks as follows:

edd at max:~$ apt-cache policy r-base
r-base:

I could have 3.2.2 from the distro -- which makes sense as 15.10 had a cutoff
some time last summer -- all the other thanks to Michael rebuilding the ports
of why I stick into Debian.
