Hi Luigi,

I would not call this a standard protocol. I would say, it is a 1.5 year old 
blog telling you how to use a beta feature (at the time of writing) of 
ChromeOS to install R and RStudio on ChromeOS.

This would have been interesting to know the last time you had a question for 
this mailing list. On 27 May you mentioned that you are using this line

  deb http://cloud.r-project.org/bin/linux/debian buster-cran40/

In the blog, it is suggested that the Linux distribution that the Chromebook 
runs is Debian stretch. If your Chrombook runs Debian stretch, you need to use 
a backport for stretch, not for buster. However, I am currently not providing 
R 4 packages for stretch, as I do not run stretch systems any more.

What is the output of lsb_release -a on your system?

Johannes
