Problem installing R 4.3.3 in Ubuntu 20.04

Question

I have the code below to install R 4.3.3 in Ubuntu 20.04. It was working fine until last week. Today, I tried to run it; however, it results in a error.

  export R_VERSION=4.3.3

  apt-get update
  apt-get install -y --no-install-recommends \
    software-properties-common \
    dirmngr \
    wget
  wget -qO- 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 \
    "deb https://cloud.r-project.org/bin/linux/ubuntu $(lsb_release -cs)-cran40/"
  apt-get update
  apt-get install -y --no-install-recommends \
    r-base=${R_VERSION}* \
    r-base-core=${R_VERSION}* \
    r-base-dev=${R_VERSION}* \
    r-recommended=${R_VERSION}* \
    r-base-html=${R_VERSION}* \
    r-doc-html=${R_VERSION}* \
    libcurl4-openssl-dev \
    libssl-dev \
    libxml2-dev \
    libcairo2-dev \
    libxt-dev \
    libopenblas-dev \
    libharfbuzz-dev \
    libfribidi-dev 

I have tried multiple suggestions from the solutions on here (i.e. ask ubuntu) without success.Like installing the version directly: apt-get install -y --no-install-recommends r-base-core=4.3.3-1.2004.0. The error:
