1. Concrete operation
Let's take Ubuntu 16.04 as an example. Directly in the command line interface, enter the following command to quickly upgrade to the latest version 4.0:
Sudo suecho "deb http://www.stats.bris.ac.uk/R/bin/linux/ubuntu xenial-cran40/" > > / etc/apt/sources.listapt-key adv-keyserver keyserver.ubuntu.com-recv-keys E084DAB9apt-get updateapt-get upgrade
Let's briefly explain the above code. Sudo su means to directly use the highest permissions; echo. > >. It means to write a line of statements to the last line in the following file referred to in > >; apt-get update means to reload the sources.list file, and apt-get upgrade means to update and upgrade the contents of sources.list (so we will naturally upgrade our newly added content).

Sudo lsb_release-a # to check the OS version3. Various versions of R
