[R-sig-Debian] R upgrade fails on r-cran-class

[Edwin Groot]

Hello all,
I encountered a problem using the recommended backport method to
upgrade R from 2.7.1 to 2.11.1 in a Debian lenny system.
r-base cannot install, and I tracked it down to a r-cran-class
dependency:

# apt-get install r-cran-class
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package r-cran-class is not available, but is referred to by another
package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package r-cran-class has no installation candidate

I installed backports of r-base-core and r-base-dev, but this did not
help the problem. Do I need to reinstall Debian?
