I am failing to get R 4 installed on Ubuntu. I am following the
instructions given here:

These are the errors I am getting:
parallels using ubuntu-linux-20-04-desktop:~/Downloads/fragpipe/bin$ sudo
apt install --no-install-recommends r-base
[sudo] password for parallels:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 r-base : Depends: r-base-core (>= 4.2.1-1.2004.0) but it is not going
to be installed
          Depends: r-recommended (= 4.2.1-1.2004.0) but it is not
going to be installed
E: Unable to correct problems, you have held broken packages.

This is the tail of the source.lists file:

deb https://cloud.r-project.org/bin/linux/ubuntu focal-cran40/
# deb-src https://cloud.r-project.org/bin/linux/ubuntu focal-cran40/

This is the head of executing: apt-cache policy r-base
arallels using ubuntu-linux-20-04-desktop:~/Downloads/fragpipe/bin$
apt-cache policy r-base
  Installed: (none)
  Candidate: 4.2.1-1.2004.0
  Version table:
     4.2.1-1.2004.0 500
        500 https://cloud.r-project.org/bin/linux/ubuntu focal-cran40/ Packages

        500 https://cloud.r-project.org/bin/linux/ubuntu focal-cran40/ Packages
     4.1.2-1.2004.0 500


End this is for executing apt-cache policy r-base-core

parallels using ubuntu-linux-20-04-desktop:~/Downloads/fragpipe/bin$
apt-cache policy r-base-core
