[R-sig-Debian] R 4.0 for ARM processors

[Paul Teetor]

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.

| Thank you so much for your advice. I must be misunderstanding something. I figured this would be a slam-dunk because (1) R 4.0 is the latest release, and (2) Ubuntu 20.04 is an LTS release, and (3) ARM is a supported architecture, or so I thought.

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.
