[R-sig-Debian] I simply cannot install R on Ubuntu. I don't know why.

[Judson]

Hi Prasenjit: thanks.  Here's what I found.  There's only one line in
sources.list that's not Dell-mini specific and it is

deb http://lib.stat.cmu.edu/R/CRAN/bin/linux/ubuntu hardy/

If I understand the output and asked correctly -- /etc/apt/preferences
does not exist ("no such file or directory").

But my goodness, look at the output to your third question!  Thanks.  Judson
