Issues with Ubuntu 22.04 and Installing the Latest Version of R (R 4.4.1) to Docker Image

Lauren,

Glad you made it over here. I am still 'away' but will be back soon at which
point I can re-run the sample scripts I use all the time for r2u setups on
Ubuntu (part of which involves getting R itself).

From your previous email (to me) I gathered that one issue may be the

signing key, how to install that key changed between Ubuntu 20.04 and 22.04
but we do have scripted solutions.

From your new email here I see that it ends on

E: You don't have enough free space in /var/cache/apt/archives/.

That is a HARD error message. You are asking your computer to install a
(large) package (name 'r-base' and its dependencies).  Maybe start with

   sudo apt install --no-install-recommends r-base-core

You can precede it with 'apt-cache policy r-base-core' (as I had mentioned
before) to see whether you have the right repo and version available.

Overall, I think you are very close in the somewhat technical quest of adding
the CRAN/R repo to another container.

Good luck,  Dirk
