I've been trying without success to upgrade R in my Ubuntu 16.04 from 3.4 to the latest version in order to install some packages. Following some solutions, I did a purge by removing all r-*. then everything broke.
I tried to install it again, but mistakenly, I've put the wrong source deb https://cloud.r-project.org/bin/linux/ubuntu focal-cran40/ instead of deb https://cloud.r-project.org/bin/linux/ubuntu xenial-cran40/ as I have 16.04
I followed many suggestions to fix it and install R again (like this, this and this) but nothing worked and I am unable to install it again!
How I tried to install the complete R system:
sudo apt purge r-base* r-recommended r-cran-*
sudo apt autoremove
sudo apt-get update

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

The following information may help to resolve the situation:
The following packages have unmet dependencies:
r-base : Depends: r-base-core (>= 4.0.2-1.2004.0) but it is not going to be installed
Depends: r-recommended (= 4.0.2-1.2004.0) but it is not going to be installed
Recommends: r-base-html but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Although that R complete system is not installed, I tried to obtain the latest R 4.0 packages as
