Answer 1

I am using Ubuntu 18.04, for this there should be a single source deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran40/ in /etc/apt/sources.list Unfortunately, I added deb https://cloud.r-project.org/bin/linux/ubuntu focal-cran40/ by mistake which I removed to install R 4.0 R is successfully installed now.
