Ubuntu – Problem installing R 4.0 on Ubuntu 18.04

r

R released an upgrade to version 4.0 about two weeks ago. I am trying to update R on my ubuntu 18.04 work station (sudo apt install r-base), but I am told that "r-base is already the newest version (3.6.3-1bionic)". But that isn't the newest version. How can I get the installer for R 4.0?

    Ubuntu usually packages software versions that are the ones that they tested, so when they are going to do a Ubuntu release, they get all stable packages one day and after that, they start testing all the packages so they ensure good reliability so they don't update those packages in their repos, that's way you won't get latest packaged inside ubuntu's repos

    and for installing latest versions of some packages you could add repos, download snaps or just rely on the good old deb

    here is how you can download latest R

    First, you should run: this will remove R

    $ sudo apt remove r-base
    

    then type this, so you can add the GPG Key

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

    Now add this repo

    $ sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran40/'
    

    then update your packages list

    $ sudo apt update
    

    now install R

    $ sudo apt install r-base
