I am trying to install R on Ubuntu 14.10
When I am giving the command to download r-base, I get the following error
roy@laptop:~$ sudo apt-get install r-base
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
r-base : Depends: r-base-core (>= 3.1.2-1precise0) but it is not going to be installed
Depends: r-recommended (= 3.1.2-1precise0) but it is not going to be installed
Recommends: r-base-html but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
What can I do? I found adding backports of raring could help. I tried several servers, but I'm getting a 404.
Here are the following changes I brought in /etc/apt/sources.list
## R
deb http://cran.cnr.Berkeley.edu/bin/linux/ubuntu precise/
## Raring backports
deb http://us.archive.ubuntu.com/ubuntu/ raring-backports main restricted universe multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ raring-backports main restricted universe multiverse

Step 1:
You can use any of the below in your /etc/apt/sources.list file to get the latest copy of R, replace <my.favorite.cran.mirror> by the actual URL of your favorite CRAN mirror. See http://cran.r-project.org/mirrors.html for the list of CRAN mirrors.
deb http://<my.favorite.cran.mirror>/bin/linux/ubuntu utopic/
or
deb http://<my.favorite.cran.mirror>/bin/linux/ubuntu trusty/
or
deb http://<my.favorite.cran.mirror>/bin/linux/ubuntu precise/
or
deb http://<my.favorite.cran.mirror>/bin/linux/ubuntu lucid/
Step 2:
To install the complete R system, use below on command line:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9
sudo add-apt-repository ppa:marutter/rdev
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install r-base
