This question of mine is now solved, thanks to a suggestion by Homer Strong, the organizer of the R user group in Portland, Oregon.
The "unmet dependencies" as reported by install was caused by an incorrect entry in /etc/apt/sources.list. Previously I had deb http://<my.favorite.cran.mirror>/bin/linux/ubuntu hardy/ It should say lucid, deb http://<my.favorite.cran.mirror>/bin/linux/ubuntu lucid/ Once it's changed, the apt-get works without a glitch. Thanks again to Homer.
