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

Fine. So, there is no apparent reason for r-base-core to be "pinned" at 2.6.2-2.

As Michael noted, cmu has r-base-core_2.9.0-2hardy0_{i386,amd64}.deb.
Do the following:

$ sudo apt-get update

If you get any signature/security warning, follow the steps under
"SECURE APT" as provided here:
http://lib.stat.cmu.edu/R/CRAN/bin/linux/ubuntu/
Then (again) run:

$ sudo apt-get update

Finally:
$ apt-cache policy r-base-core

If the candidate version is correct, do

$ sudo apt-get install r-base-core

r-base and r-recommended can be ignored for now. If nothing else, then
you can brute force the process as Michael described.
