Hello:

I have a new install of Ubuntu 12.04. I have tried to install R via source,
apt-get, and the deb packages from a cran mirror. Each of these had issues.
I followed the secure apt key install. The apt-get and deb installs each 
have the same error. So, let's ignore the source install for now. This is the error:

>> sudo dpkg -i r-base-core_2.15.1-1precise2_i386.deb
(Reading database ... 244318 files and directories currently installed.)
Preparing to replace r-base-core 2.15.1-1precise2 (using r-base-core_2.15.1-1precise2_i386.deb) ...
Unpacking replacement r-base-core ...
dpkg: dependency problems prevent configuration of r-base-core:
 r-base-core depends on tk8.5 (>= 8.5.0); however:
  Package tk8.5 is not installed.
dpkg: error processing r-base-core (--install):
 dependency problems - leaving unconfigured
...
 r-base-core

Or, with apt-get

>> sudo apt-get install r-base-core
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-core : Depends: tk8.5 (>= 8.5.0) but it is not installable
               Recommends: r-recommended but it is not going to be installed
               Recommends: r-base-dev 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.

Obviously the hurdle here is tk8.5. I installed 
ActiveTcl8.5.12.0.296033-linux-ix86-threaded.tar.gz from 
http://www.activestate.com/activetcl/downloads, which www.tcl.tk
suggested for obtaining binaries. This however did not make R
any happier. Any suggestions would be greatly appreciated.

Thanks,
kc
