[R-sig-Debian] Failing to install R 4.0.? on Raspian

Wed Mar 24 16:00:42 CET 2021

Hm, doesn't that third line make the heroic assumptions that there were a
non x86_64 repository?  So I think the error below may be a side effect.

Just because you are getting armhf packages from some repositories does not
imply you get them from all, methinks.  apt may happily look at the
binary:all packages which it could install, but then get sidelined by their
dependencies which it may not.

| The following actions will resolve these dependencies:
| 
|      Keep the following packages at their current version:
| 1)     r-base [Not Installed]                             
| 2)     r-base-dev [Not Installed]                         
| 3)     r-cran-boot [Not Installed]                        
| 4)     r-cran-codetools [Not Installed]                   
| 5)     r-recommended [Not Installed]                      
| 
|      Leave the following dependencies unresolved:         
| 6)     r-base-core recommends r-recommended               
| 7)     r-base-core recommends r-base-dev      
| 
| I assume that I have some part of R 3.5.? stuck in the apt system from previously installing R from 
| the default raspian repositories (stupid of me).  There is nothing in /usr/lib/R (no directory) nor
| does /usr/bin/R exist and I have (in desperation: not something I remember doing often with Debian 
| machines) even rebooted the machine but no change.
| 
| I could wipe the machine and start over and not install R until after adding the buster line
| deb http://cloud.r-project.org/bin/linux/debian buster-cran40/
| to /etc/apt/sources.list and doing apt-get update
| 
| However, I thought I'd check things out here first. Thanks in advance for any suggestions.
