Thank you very much, Dirk. That nudge solved the problem, of course. I am embarrassed. I was so fixated on Ubuntu repositories that I neglected to check the Debian 'testing' world! Regarding the RPi: The RPi 4 uses the 'arm64' architecture, the full 64-bit one. I stopped using dedicated distros, such as Raspian, when Ubuntu went all-in on RPi support, which happened in their newest release focal (20). The dedicated distros often have an unhelpful attitude -- e.g., "you should use *this* package, not *that* package" -- that doesn't work for me.

Don't snicker. Hey, it's got 16 cores, 16 GB RAM total, and a | terabyte of space. And it's paid for, no monthly fee. When I look at the build pages for my packages, eg this one for r-base ? https://buildd.debian.org/status/package.php?p=r-base I see three (3) different arm labels: arm64, armel, armhf. I have no idea what the Pi uses, and never looked closely, but I am at least vaguely aware that there are apparently entire _dedicated_ distros and installers based on the Debian builds.? Raspian is one name that comes to mind.? Did you try that? Also, one second of Googling leads to: https://ubuntu.com/download/server/arm Good luck, keep us posted -- other architectures/platforms can be fun.

Hmmmm. Perhaps I'm using the wrong terminology. My logic is: (1) I am running Ubuntu focal on the cluster. (2) Ubuntu focal is built on Debian bullseye but (3) Debian bullseye is not yet the stable release; it is the 'testing' release; hence (4) I will pull the r-base-core package from the 'testing' version of Debian. And, in fact, I found r-base-core for 4.0.2 in the bullseye distribution. Does that all make sense? My RPi cluster sits on the file cabinet next to my desk, all four boards. Yes, you could argue that it's merely a toy.... but it's bigger and cheaper than the AWS box that currently hosts my web site, RStudio server, and Shiny server! For the truly curious, you can view my RPi cluster here:?https://photos.app.goo.gl/kALwoYCVxJ32VgxEA Thanks again, Dirk. Your contributions to Debian and Ubuntu are foundational for my computing platforms.
