R help - Feb 2013 - upgrading r-base

I'm trying to install R 2.15 on an Ubuntu server.  I'm getting the
"depends
.... but it's not going to be installed" error messages I've seen
people
write about, but never solve.  I've attached a screen shot, if that helps.
Has anyone seen (and solved) these updating issues?  I find it hard to
believe that everyone using Ubuntu server is an R version behind.  Thanks
for your time.

Have you looked at the instructions at the URL which Sarah Goslee
drew to the attention of the list on 19 July 2012?

version.

You probably need to modify your /etc/apt/sources.list file in the
manner suggested in those instructions.

     cheers,
