So sorry, at the moment, arm packages for current R are not on CRAN. For the moment, you can install R 3.5.2 from buster, or compile "locally", with apt-get build-dep r-base apt-get source -b r-base and install the packages that hopefully will appear. Johannes P.S.: Of course, if someone would once again upload R to buster-backports (and after the release of bullseye to bullseye-backports), this would be no problem any more. But that depends on one of the Debian devs to decide they want to maintain such a backport.> > Dirk > > | root at www:~# > | > | and added the key using > | > | apt-key adv --keyserver keys.gnupg.net --recv-key > | 'E19F5F87128899B192B1A2C2AD5F960A256A04AF' > | > | following > | https://cran.r-project.org/bin/linux/debian/#debian-buster-stable > | > | apt-get update > | > | runs fine but apt install -t buster-cran40 r-base gets me this: > | > | root at www:~# apt install -t buster-cran40 r-base > | Reading package lists...

SO embarrassing. I had completely forgotten that it was an ARM CPU!!! Anyone got any advice on getting R 4.0.? (and then shiny I was hoping) onto ARM? Would I have to roll my sleeves up and compile? I suspect that's not a good route for me but I will certainly give it a stab if there aren't easier options. (I have searched and they're not leaping out at me!)
