R SIG Debian - Jul 2024 - Issues with Ubuntu 22.04 and Installing the Latest Version of R (R 4.4.1) to Docker Image

No sure why you?re doubting me but if one would like the minimal Dockerfile
following the CRAN recommendations at
https://cloud.r-project.org/bin/linux/ubuntu/, one would simply do

FROM ubuntu:22.04

USER root

ENV DEBIAN_FRONTEND noninteractive

## Configure Ubuntu for R install
RUN apt update \
    && apt install -y --no-install-recommends \
    software-properties-common \
    gnupg2 \
    wget \
    && wget -q -O -
https://cloud.r-project.org/bin/linux/ubuntu/marutter_pubkey.asc \
    | tee -a /etc/apt/trusted.gpg.d/cran_ubuntu_key.asc  \
    && add-apt-repository -y "ppa:marutter/rrutter4.0"

## Install R
RUN apt update -y \
    && apt install -y r-base\
    && apt clean \
    && apt purge \
    && rm -rf /var/lib/apt/lists/* /tmp/*


Benefits of using Michael Rutter?s repo is nightly builds but importantly for
folks on dual architectures a built for both Amd64 and Arm64, which allows for
cross-building for different metal like folks doing development using docker on
Macs then pushing to cloud base resources using x86.

However, one would probably want to add a C/C++ compiler to the base (hence
build-essential) for downstream package installation as well as frequently used
libs in R packages (hence libcurl4-openssl-dev and libxml2-dev).

Just my 2 cents.

I am not sure about that.

For jammy, my current (and used) rocker/r2u:jammy Dockerfile is
   https://github.com/rocker-org/r2u/blob/master/jammy/Dockerfile
and it does what Laurent want (plus a bit more: r2u setup) but I have
been traveling since she first emailed me and have not run it to confirm.

I am aware. I co-wrote those instructions. The Dockerfile I pointed to is
newer, and regularly used by me and others.

I still think you continue to answer questions that Lauren did not ask:
nobody has stepped in to replicate _her issue_ starting from a different
container. But inasmuch as you also try to help it is of course appreciated.

But maybe it is time to wait for Lauren to chime about what works, and what
doesn't.
