[R] Ubuntu sources file for R packages

[Lennart Kasserra]

Hi Naresh,

the README you linked to points you to the r2u-project (https://github.com/eddelbuettel/r2u), which has setup scripts & instructions for how to setup binaries for CRAN packages and most recent R version on Ubuntu, including on 26.04 in the new format. Here is the script for 26.04 LTS: https://github.com/eddelbuettel/r2u/blob/master/inst/scripts/add_cranapt_resolute.sh, all instructions worked fine on my machines running Ubuntu 26.04 LTS.

All the best,
Lennart
