Updating R 3.5.3 to R 4.0.2 on Ubuntu 18.04

Question

I have been trying to move from this version for a while, however all attempts have failed. The steps I am following:

sudo apt-get remove r-base r-base-dev
sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/'

output:

Err:13 http://ppa.launchpad.net/grass/grass-stable/ubuntu bionic Release     
404  Not Found [IP: 91.189.95.83 80]

after:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9 

output:

after:

sudo apt install r-base r-base-core r-recommended

output:

Solution

You have to remove problematic PPA (it does no publish packages for 18.04 LTS - bionic) first with:

sudo add-apt-repository -r ppa:grass/grass-stable

and then update your package lists

sudo apt-get update

and install new updates with their dependencies by

sudo apt-get dist-upgrade

---

You have added R 3.5 repository (see bionic-cran35 in its URL), instead of needed R 4.0 (bionic-cran40). You have to remove wrong repository with

sudo add-apt-repository -r 'deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/'

and then add correct one:

sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran40/'
sudo apt-get dist-upgrade
sudo apt-get install r-base r-base-core r-recommended

I update various python packages, but not R. After following their steps, I ran: "sudo apt-get install r-base-core". Again, I am in version 3.5.3

[biologistor]

After "sudo apt upgrade r-base r-base-dev", I get: r-base-dev is already in its latest version (3.5.3-1bionic). The following packages have unmet dependencies: r-base: Depends: r-recommended (= 3.5.3-1bionic) but will not install E: Broken packages

See update above.

r-base: Depends: r-base-core (> = 4.0.2-1.1804.0) but 3.5.3-1bionic is going to be installed Recommends: r-base-html but will not install r-recommended: Depends: r-base-core (> = 4.0.2-1.1804.0) but 3.5.3-1bionic is going to be installed Depends: r-cran-mass but will not install Depends: r-cran-class but will not install Depends: r-cran-nnet but will not install Depends: r-cran-spatial but will not install E: The problems could not be corrected, you have retained broken packages.
