R upgrade fails on r-cran-class
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? Diagnostic information: # uname -a Linux MyNotebook 2.6.26-2-amd64 #1 SMP Tue Jan 12 22:12:20 UTC 2010 x86_64 GNU/Linux
