[R-sig-Debian] Installing R 4.1.2 doesn't work as it did a week ago

[Chad Young]

I have a docker file for installing R on Ubuntu 18.04, and as of last week
it is failing. I think it seems to be related to the recent release of R
4.2.0. I want to install R 4.1.2, but when I use the below command and then
check the R version, it comes out as 4.2.0. Do you know why this is
happening?

RUN apt-get update \
    && apt-get install -y gnupg2 software-properties-common \
    && apt-key adv --keyserver keyserver.ubuntu.com --recv-keys
E298A3A825C0D65DFD57CBB651716619E084DAB9 \
    && add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu
bionic-cran40/' \
    && apt-get update \
    && apt-get install -y \
           r-base=4.1.2-* \
           r-recommended=4.1.2-*

If I just install r-base-core=4.1.2-* it seems to install the correct
version of R.
