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.

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. I am confused by these two paragraphs. Are you planning to use Debian 'testing' on you Raspberry Pi, or Ubuntu 'focal' aka 20.04? And out of curiousity, is that a hosted machine?? Typically these are toy-sized and usually at home.

Of course you will need to rebuild after R releases to keep up to date. Johannes
