The issue may be the use of the the "safe-upgrade" option. The first thing is that I don't think apt-get has a "safe-upgrade" option. Are you using aptitude or the "dist-upgrade" option in apt-get? I think you can solve the problem by just using "apt-get upgrade". I don't know why it is blocking MASS, but something in the "safe/dist-upgrade" procedure is holding it back.
Sorry; I was using aptitude safe-upgrade. uclid: ~ # apt-get upgrade Reading package lists... Done Building dependency tree Reading state information... Done The following packages have been kept back: r-cran-mass 0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded. Searching a bit, I discovered aptitude why-not: aptitude why-not r-cran-mass i r-base Depends r-recommended (= 2.15.0-1lucid0) i A r-recommended Depends r-cran-mass p A r-cran-mass Conflicts r-cran-vr p A r-cran-mass Provides r-cran-vr euclid: ~ # But now I'm not sure what to do to fix this.

Remove r-cran-vr. This was a virtual package that made sure class, MASS, nnet, and spatial were installed. It is no longer needed. So if you remove that, you should be good to go. Or use "apt-get upgrade". Michael
