How to install RAR on Ubuntu 18.04

To install RAR on Ubuntu 18.04

RAR files are compressed files created by the WinRAR archive. RAR files can be split into multi-volume archives when dealing with large file sets. Like Zip files, these files need to be extracted. In this tutorial, the method to install RAR on Ubuntu is covered. 

Installing  RAR

Let us first start with adding a repo by making use of the following command. 

root@linuxhelp:~# add-apt-repository ppa:eugenesan/ppa
 This repository contains collection of customized, updated, ported and backported
packages for two last LTS releases and latest pre-LTS release.
Packages for older releases relocated to ppa:eugenesan/archive or deleted.
