R SIG Debian - May 2020 - Install R 4 on Chromebook (unmet dependencies)

Hello,
I have tried to upgrade R to 4.0. I have added `deb
http://cloud.r-project.org/bin/linux/debian buster-cran40/` to
`/etc/apt/sources.list` (but I removed cran35). Btu when I run
`apt-get update; apt-get install r-base r-base-dev` I get an error. I
think it depends on r-base-core, since it depends on these obsolete
libraries:
```
$ sudo apt-get install r-base-core
Reading package lists... Done

Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

How can I upgrade these libraries on Chromebook?
Thank you

Hi,

I assume you are running Debian stable on this chromebook (True?). What's
the
architecture you are using (like amd64 or arm64, you can see it in the output 
of uname -a). I have stopped providing binaries for arm architectures, as I am 
not using them. You could build R 4.0.0 packages from source, though...

If you were on a supported architecture, you would need to use -t buster-
cran40 for apt install, as mentioned in the Debian page on CRAN.

Kind regards,

Johannes
