| 
| deb http://cran.wustl.edu/bin/linux/ubuntu trusty/
| deb http://ports.ubuntu.com/ubuntu-ports/ trusty-backports main restricted
| universe
| 
| (Note: I've tried a couple different R mirrors and it doesn't affect

| 
| 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:
| 
| sudo apt-get install r-base
| Reading package lists... Done
| Building dependency tree
| Reading state information... Done

| The following information may help to resolve the situation:
| 
| The following packages have unmet dependencies:
|  r-base : Depends: r-base-core (>= 3.2.4-revised-1trusty0) but it is not
| going to be installed
|           Depends: r-recommended (= 3.2.4-revised-1trusty0) but it is not
| going to be installed
|           Recommends: r-base-html but it is not going to be installed
|           Recommends: r-doc-html but it is not going to be installed
| E: Unable to correct problems, you have held broken packages.
| 
| 
| Using sudo apt-cache showpkg <package> reveals that apt is attempting to
| install r-base 3.2.4, but only has access to r-base-core 3.0.2.  It does
| have access to r-recommended, r-base-html, and r-doc-html all version 3.2.4
| though.

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:
  Installed: (none)

edd at max:~$ 

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.
